Using a Genealogical Proof Argument

My ancestor Isabella Sievewright, mother to 15 and wife of John Rose (1804-1884) was a most irritating woman. Why did she have to die in 1850, leaving her only footprints at her marriage in Southampton in 1825 and her 1841 census record showing that no, she wasn't born in the County of Southampton (now Hampshire)? 

With 15 children, the slight majority living to adulthood, it is not surprising that many family historians were keen to find out who she was and where she came from. I had been puzzling for 12 years and others for even longer. When I finally worked it out, I attempted to add it to Wikitree and received a very rude response from a man who had added a different Isabella's baptismal record and ascribed her to different parents. I complained to the administrators and they followed it through and deleted his public response but left the tree as it was, so I was unable to take her tree further back. 

Therefore, I decided to write a "genealogical proof argument" to see if I could persuade the administrators to take me seriously. I had learned how to write these through watching a webinar last year. It was presented by Cyndi of CyndiList fame. 

 Here it is: 

I do not believe that Isabella Sievewright who married John Rose in Southampton in 1825 was the daughter of Robt. and Mary Sievewright of St Botolph without Algate, as recorded on the tree above. I have developed a Genealogical Proof Argument to state my case as below: 

Genealogical proof argument

Isabella Sievewright (1806-1850) 


Who was Isabella Sievewright, where and when was she born and who were her parents? 


Since Sievewright is a Scottish name and far less common in England, she could have been born in Scotland or be of Scottish heritage. 


Isabella Sievewright, born in 1806 at St Luke, Finsbury, London was the daughter of Alexander Sievewright and his wife Isabella Watson. They were both born in Dundee, Scotland and had two other children, Margaret and Alexander, also both born in Dundee. The baptismal record was badly transcribed as Swewright. Isabella Sievewright married John Rose in Southampton in 1825 and bore him 15 children. This conclusion differs from Isabella’s parentage shown on Wiki Tree at https://www.wikitree.com/wiki/Sievewright-35

The problem 

Since Isabella died in 1850, she appears in only one census, that of 1841. The census states that she was not born in the County of Southampton (later called Hampshire). The marriage certificate includes no other information apart from their names and suggests they were both of full age. No parentage is listed for her.

Her age is recorded inconsistently on her death certificate and the 1841 census. 


Some of Isabella and John Rose’s children were baptised with middle names which looked like surnames. These included Watson, Thane, Martin and Sievewright. Could these middle names have been ancestors of either John or Isabella? These children were: 
  • James Martin Rose (1826-1857) 
  • Alexander Thane Rose (1830-1848) 
  • David Martin Rose (1831-1833) 
  • Charles Watson Rose (1834-1904) 
  • Francis Watson Rose (1834-1899)
  • Samuel Saint Rose (1835-1905) 
  • Isabella Sievewright Rose (1840-1881) 
The author is a descendant of George Henry Rose, the second son of Isabella Sievewright and John Rose. Additionally, a granddaughter of Isabella Sievewright, Alice Rose (1857-1935) b. Southampton, daughter of George Henry Rose married (in Southampton) Francis Watson Young of Dundee in 1877, and established her marital home in Dundee, Scotland . 

Could this be a clue? This hint was reinforced when David Young’s heritage was researched. His mother was Margaret Ann Sievewright (1817-1998), born in Dundee to Alexander Sievewright and Isabella Watson. Margaret Ann Sievewright’s paternal grandmother was Christian Thain (1752-1788). In other words, three of the names which appeared as middle names in John Rose and Isabella Sievewright’s family. Could Margaret Ann Sievewright, born in Dundee to an Alexander Sievewright and Isabella Watson have been Isabella Sievewright’s sister? There was also another sibling, a son Alexander born in Dundee to the same couple in 1813. 

Alexander Sievewright and Isabella Watson’s marriage could not be found in Scotland. However, Alexander Sievewright was recorded as living in Poplar, London in 1812 with his occupation being recorded as commander of the ship Fame. Eventually, their marriage was found at St Luke, Finsbury, London on 27 December 1805. 

Could Isabella have been baptised at the same church? This was another stumbling block since no researchers have been able to find a baptism. However, after searching for an Isabella, born to an Alexander and Isabella at St Luke, Finsbury without a surname, eventually her baptism was found. The surname had been very badly transcribed by Ancestry as “Swewright”. The original record of baptism shows that the surname was Sievewight. The record records Isabella’s birth as 6 November 1806 and her baptism as 4 January 1807. 

DNA evidence 

As well as the conclusions reached due to the marriage between my 2x great aunt Alice and her first cousin once removed (1CR1) Francis Watson Young, there are common DNA matches between the author, Margaret Elizabeth Tucker (1947-) who is Isabella Sievewright’s 3x great granddaughter and another descendant of David Watson (1737-1808) and Isabell Matthew (1745-1828) who are Isabella Sievewright’s paternal grandparents. This match is also a 5x great-grandson of David Watson and Isabell Matthew. 


The WikiTree administrators have noted that the original baptismal information was Contested, have made me the manager of Isabella Sievewright's ID and I can now add her ancestors.

So it pays to Check It Out.
