I think that being a Jew is passed on through the mother.
Catherine Walker Burns Rose born illegitimate, 27th April 1908 at 10 Milne Court, Lawnmarket, Edinburgh father John Rose ‘Licenced Pedlar’ mother Catherine Walker Burns ‘Confectioner’
In 1911 in Dundee, Catherine Walker Burns Rose is with her mother, aged 23 and father aged 24 now listed as a 'Hawker of Hardware’ and has 2 younger siblings Jessie 19 months and Charles 1 month. The parents are listed as married, but I can't find evidence of that.
I followed up on that census entry, and found a death certificate in Dundee for the same year (23rd July 1911) for John Rose aged 24 years, death informant Katie Walker (Inmate). There is a possibility that this is the correct John Rose.
Against the argument...... He is described as ‘Assistant at the Roller Skating Rink’ (single)
For the argument..... The informant. His age is correct. His father’s occupation is described as ‘Hardware Hawker’ (Deceased) the same occupation as John Rose had declared on his 1911 census.
The plot thickens..... If this is the correct John Rose, then I am sure he is from a Jewish family. Which ties in with the programme, Catherine Walker Burns Rose, married in the Synagogue, after converting to the faith, so if I’m correct with her father, she was half Jewish anyway.
This death certificate lists his Parents’ as Abraham David Rose, ‘Hardware Hawker’ (deceased) and Rebecca Lindey.
Further research shows this family living in Edinburgh in 1901, Parents both born in Germany, as was John and his two older siblings (Harris and Isabella), his three younger siblings (Solomon, Lea and Israel) having been born in Edinburgh.
