Jaywit & all
Yep, something doesn't add up at all? The info I was given a while ago was that John Daniel Stephen Dobson (my Gt.Gt. Grandfather) married a Mary Ann Waller who names her father as Daniel Brant. The reason appeared to be (and feel free to correct it please!!!) that Mary Ann was a widow of a Richard Thomas Waller. I cannot find a Waller - Brant marriage? This Summer name now has me confused, but not for the first time with this branch!!
The only "facts" that ring true are John D S Dobson was a Gasfitter, as noted oh John Vorwerg Dobson birth certificate. Later John D S Dobson and family move from London to Liverpool, where John D S dies in 1863, assumed to have been some kind of work related accident as his now apparently twice widowed wife Mary Ann was in receipt of a pension from the Gas Company.
John V Dobson appears on the 1871 (aged16) census living with Mary Ann and two elder sisters in Liverpool. John Vorwerg Dobson disappears and a John William Dobson appears. John William Dobson marries Ellen Waters in 1878 and names John Dobson (Gasfitter) as his father. John Vorwerg appaers to have become John William around the time of the Franco-Prussian war, when there was a lot of anti-Germanic feelings growing, so he Anglicised his name.
It's a puzzle alright!
