Daniel Marshall

Just checked my notes and the births for a Mary and Daniel came from census returns, they were described as aunt and uncle of Alexander's children

According to SP's death index there was at least 1 possibly 2 families with the surname Marshall about the same time as your ancestors
1 with mother's ms Dickson
The other possibility is mothers ms Neilson
Do either of these surnames appear in your family

Hi Craig,

Mary may have married Daniel, rather than being brother and sister. So she wouldn't be a Marshall by birth.

Hi Wendy, neither of those names are familiar, but I will look into it.
As far as Daniel and Mary being married, it doesn't appear that way, Daniel and Mary are living with their mother in 1841, they then appear in 1851 census Daniel is listed as head and Mary as sister,
