Thanks. I am not sure that that adds up given what I already have.
Not surprising. If you try to add two (James Brock and Ann McCartney) and two (James Brock and Mary Fletcher) you are bound to get five.
The John Brock I have was born to James & Ann Brock (McCartney)
1818 April 13th b May 2nd John Brock, Calton, Barony, Scotland
Yes, so far so good. There is a family in Warwick Street, Glasgow in 1841 comprising James Brock, Ann Brock,
John Brock, aged 20, Jane Brock, 20, Eliza Brock, 15 and Sarah Ann Brock, 9. These match the names and ages of the children of James Brock and Ann McCartney. I have already pointed out that the names Ann and Agnes are used interchangeably, that Sarah A, 18, is with James and Ann Brock in Glasgow in 1851, and that Ann McCartney or Brock died in Glasgow in 1881. Therefore not only did Ann McCartney not die before 1832, she was alive and living with her husband in Glasgow 18 years later, and she lasted another 30 years after that. John's age is spot on for the son of James Brock and Ann McCartney, because adults' ages were supposed to be rounded down to the nearest 5 years in 1841. Therefore it looks as if the John Brock living with James Brock and Ann McCartney is their son and it follows that the one living with James Brock and Mary Fletcher is
not the son of Ann McCartney.
A John Brock appears on the 1841 census see below he is 22 and the parents are listed as James & Mary Brock (Fletcher)
No. He is
in the same household as James Brock and Mary Fletcher. There is nothing to say that he is the son of either. If he is James' son he is unlikely to be Mary's, as James and Mary had only been married 8 years and he is 22, so this James Brock may well have been married twice, but his first wife is not Ann McCartney. John could even be Mary's son by her first husband, having taken his stepfather's surname.
I don't understand why you are so determined that the James Brock who married Ann McCartney is the same person as the James Brock who married Mary Fletcher or Wright. The 1851 census says that all the latter's family were born in
Hamilton, while the children of James Brock and Ann McCartney were born in
Glasgow (Calton/Barony/Gorbals). This on its own is enough to show that they are two different families, even without the overlap of dates.
1836 Dec 19th a female child to James Brock, born in Glasgow? Not sure of whether this is part of this family or not.
As this child was born in Glasgow, not in Hamilton, it is more likely that she was another daughter of James Brock and Ann McCartney than that she was a daughter of James Brock and Mary Fletcher.
The one thing I really did wonder about was that it says he was a shopkeeper for the first marraige, when later he was a weaver and that seems more likely.
It makes perfect sense unless you think they are the same individual.
