Frances, it would be helpful if you would explain to Nicole how you know that Margt White was the daughter of Jacob White + Mary Callow when she doesn't appear on the IGI (that I could see) and had married before the 1841 census, so that she can include sources in her records? Did the 1835 marriage have fathers' names included, and, in which case, what was David's father's name?
Thanks.
Sue
