Cecelia Maria du Plessis

[TREE] Added 2026-07-31 by kin_sweep.py under the one-degree rule: spouse of Petrus Jacobus TheronL. Thin record, name, dates and the family link only. NO PLACE IMPORTED: the tree's place strings are systematically wrong and are not evidence.

*** [22 Aug 2026] HER DEATH NOTICE (DOC-0333, SRC-542) IS NOW HELD AND IT IS A PRIMARY SOURCE FOR NEARLY EVERYTHING ON THIS ROW. *** Died TENTH APRIL 1895 - the date this row already carried, now documented rather than compiled. Aged 38, which agrees with 9 January 1857. Usual place of residence RONDAVEL, KLAARSTROOM, WARD KREDOUW; died there; BURIED ON THE FARM. Occupation given as Housewife, birthplace as 'Cape Colony' - no more precise. Cause of death CONSUMPTION after five months' illness, attended by DR STEVENSON of Prince Albert. Registered at Prince Albert 10 May 1895, entry 37, by her husband P J Theron.

*** THE FORM CORROBORATES THE MODEL'S CHILDREN TO AN EXTRAORDINARY DEGREE. *** It gives eight living daughters aged 17, 15, 10, 8, 7, 6, 4 and 2 - and the eight daughters held here, aged at 10 April 1895, are 17, 15, 10, 8, 7, 6, 4 and 2. Eight independent ages, no discrepancy.

BUT IT NAMES ELEVEN CHILDREN AND THIS MODEL HOLDS TEN. See LEAD-0268.

*** [22 Aug 2026] SHE MARRIED INTO OCKERT ALMERO AND ADRIANA CECILIA'S OWN DESCENT, AND THAT IS WHY SHE IS ON RONDABEL. *** Her husband Petrus Jacobus TheronL (PER-000384) is a GRANDSON of Ockert Almero OosthuizenL and Adriana Cecilia VenterM: his mother DINA MAGDALENA OOSTHUIZEN (PER-000132, 1832-1908) is their twelfth child. So her ten children are Ockert Almero and Adriana Cecilia's GREAT-GRANDCHILDREN, and she stands 4 steps from Johannes Adriaan OosthuizenM and 9 from the anchor. The tie is AFFINAL for her and consanguineous for her children.

*** [23 Aug 2026] DU PLESSIS IS IN THE DIRECT LINE, ONE STEP ABOVE THE VENTER SIBSHIP. *** Martha du PlessisM (PER-000750, 1730-1796) married Petrus VenterM on 14 October 1753; their son JAN LOUIS VENTER (PER-000120, b.1754) fathered the sixteen Venter children of STO-0046 - among them Adriana Cecilia, who married the root Oosthuizen, and Maria Catharina, who held Rondabel by 1829. So Martha is the grandmother of the root matriarch, and a du Plessis reaching Rondabel is not merely a coincidence of a common surname.

Superseded: answered below TWO OTHER DU PLESSIS TOUCH THAT FARM AND NEITHER IS JOINED TO HER HERE: Ignatius Michael (PER-000050, d.1818), whose Rondabel the inventory places ON THE TARKA, 380 km east and probably a different farm; and Cecilia Maria (PER-001346), who died on the Koup Rondabel in 1895 and has no parents recorded at all. LEAD-0272.

*** [23 Aug 2026] HER PARENTS ARE KNOWN: JOHANNES GYSBERTUS DU PLESSIS (PER-001879, 1826-1913) AND JOHANNA ELIZABETH VAN ROOYEN (PER-001880, 1831-1913). *** [FS], from a fan chart, with her ancestry four generations back - 24 rows, PER-001879 to PER-001902. LEAD-0267 closes.

Her son Johannes Gysbert TheronH (PER-001169) carries her father's name, which is the naming pattern confirming the parentage without being asked.

Superseded: answered below THE LINE MATTERS BEYOND HER: it runs back to DANIEL DU PLESSIS (1732-1795), a near-exact contemporary of Martha du PlessisM (1730-1796), the grandmother of the root matriarch and of the Venter woman who held Rondabel in 1829. If those two are siblings, the du Plessis buried on that farm is kin to the du Plessis whose granddaughter held it. Unproven - LEAD-0272.

Her second great-grandfather on the same chart is HERMANUS STEYN (PER-001899, 1743-1804), rendered there as 'President Hermanus SteynM' - the Swellendam republic of 1795. [TO VERIFY].

Superseded: answered below *** [23 Aug 2026] TESTED AND THE ANSWER IS NO. *** FamilySearch gives Daniel du PlessisM (LC5W-J51) the parents CHARL PRIEUR DU PLESSIS (1688-1736) and CECILIA VAN MAARSEVEEN (1692-1762), married at Stellenbosch on 12 June 1712, and lists their THIRTEEN children in full: Charl 1716, Pieter 1716, Elizabeth 1716, Magdalena 1717, Johannes Jean 1720, Elisabeth 1722, Catharina 1723, Charel 1724, Philippus 1727, Jacob 1730, DANIEL 1732, Jacobus 1734, Anna Magdalena 1736. *** THERE IS NO MARTHA. *** The 1730 place in that sequence is Jacob, and the list runs to its end rather than being truncated. So Daniel and Martha du PlessisM are NOT brother and sister on this evidence, and the near-identical dates were the coincidence LEAD-0272 warned they might be. A well-populated sibship with a date and an id on every child is not absolute proof of an absence, but it is close, and the burden now sits the other way.

*** [23 Aug 2026, CORRECTING THE SAME DAY'S OWN CONCLUSION] MARTHA DU PLESSIS AND DANIEL DU PLESSIS ARE FIRST COUSINS. *** Martha's father is JEAN LOUIS DU PLESSIS (PER-001909, 1691-1768) and Daniel's is CHARL PRIEUR DU PLESSIS (PER-001903, 1688-1736), and both are sons of JEAN PRIEUR DU PLESSIS (PER-001905, 1638-1708) and MARIE MADELEINE MENANTEAU (PER-001906).

SO THE SHARED ANCESTOR IS REAL AND THE COINCIDENCE DID NOT DISSOLVE. Jean Prieur du PlessisM is the 4x-great-grandfather of CECILIA MARIA DU PLESSIS, who died on Rondabel in 1895, and the 2x-great-grandfather of ADRIANA CECILIA VENTER, the root matriarch, and of MARIA CATHARINA VENTER, who held Rondabel by 1829.

Superseded: answered below WHAT WENT WRONG IN THE TEST: LEAD-0272 asked whether Martha and Daniel were SIBLINGS, FamilySearch's sibling list for Charl Prieur's children correctly contained no Martha, and that correct answer was read as closing the question. It closed one relationship and left the obvious next one untested. A negative result is only as wide as the question asked of it.

*** [23 Aug 2026] AND THE SHARED-ANCESTOR CLAIM IS WEAKER THAN IT LOOKS. *** JEAN PRIEUR DU PLESSIS IS THE DU PLESSIS STAMVADER AT THE CAPE, so nearly every du Plessis here descends from him and 'they share Jean Prieur' says little more than 'they are both du Plessis'. What survives is the narrow fact: MARTHA AND DANIEL ARE FIRST COUSINS, their fathers being brothers. Four to six generations back is background, not connection. LEAD-0272.

*** [23 Aug 2026] HER FATHER IS BURIED 12 KM AWAY. *** Johannes Gysbertus du PlessisM (PER-001879) lies on REMHOOGTE (GRV-1459, CEM-025); she lies on Rondavel (GRV-0021). Two du Plessis graves in one district, a generation apart.

*** [23 Aug 2026] LEAD-0275 ANSWERED: YES. JACOBUS JOHANNES PETRUS DU PLESSIS (1869-1941) IS CECILIA MARIA'S BROTHER. *** A FamilySearch family view supplied by Frans gives JOHANNES GYSBERTUS DU PLESSIS (1826-1913, KC34-PVM) and JOHANNA ELIZABETH VAN ROOYEN (1831-1913, L631-CW5), married 27 NOVEMBER 1848 AT GEORGE, with NINETEEN CHILDREN - among them CECILIA MARIA 1857-1895 (GHW4-KDS, the id this project already held) and JACOBUS JOHANNES PETRUS 1869-1941 (GHLG-66D), whose years match his Reim Hoogte headstone to the day.

SO THE MAN WHO BOUGHT ROSSEL ERF ON REIM HOOGTE No. 167 IN 1908 AND IS BURIED ON IT WAS THE BROTHER OF THE WOMAN BURIED ON RONDABEL. The du Plessis were not visitors who married into this district: the parents lie on Reim Hoogte, a son bought a portion of it, and a daughter married into the Theron-Oosthuizen circle at Rondabel.

HIS PARENTS ARE CONFIRMED TOO, matching the fan chart exactly: Daniel Jacobus du PlessisM 1802-1879 (LC5W-JYL) and Susanna Johanna Catharina van der WesthuizenM 1803-1852 (9WVN-24K), married 4 AUGUST 1822 AT GEORGE, eight children.

BOTH MARRIAGES ARE AT GEORGE, which is the district the Olifants prequel ground sat in - so this family was George-district before it was Prince Albert.

THE SIBSHIP IS NOT IMPORTED. Nineteen children is exactly the bulk 6 says not to pull; the ids are recorded here so any of them can be fetched when something ties them to this ground.
