yes that is my test tree. I have guessed at Ann being the mother on account she is living in Brighton in the 1861 census. Of course it could be the 1871 Ann is a different Ann Caddey. I matched them due to similarity of birth year. It could be wrong as I assume the Brighton Ann Caddy is the same that married a Mr Grainger in Brighton in 187x and died 1901.
I have been able to trace Noely's life from 1895. She lived with foster parents in Brighton and then Paddington, married a much older man Mr Minnis, they had no children and and died in 1947.
Sydney is my relative. He was in foster care with Evelyn in 1891 (same family Noely was with in 1911) and he was then placed in a boy's home in Liverpool before 1901. Evelyn does not show up after 1891 until the electoral records show her at Noely's adress in 1947 and then dying in 1954 unmarried.
Rosine's records I have traced are, her birth and baptismal records from1862, her name on the three children's bith records, Roseane Caddey in the 1881 census and she appears on electoral records as the housekeper to a Dutch Merchant in Kensington from 1923 to 1937. Finally she moves in with Noely and her husband in Paddington until her death in 1941. Christopher Crabb only appears on the baptismal certificate as Rosine's father not the burth certificate. The only Christopher Crabbs I can find from that time all live in Cambridgeshire and and because of the 1881 census saying Rosine is German I thought maybe it is Christoph Crabbe the German seaman, which might also explain her disappearance from UK records for long periods
I guess this could be a long project.
Thank you for the interest
