Still trying to sort out my White ancestors, and their surname is not helping! This is what I do know; Richard White and Ann Hart's son ( I am aware of their other children, but trying to sort out this one) Henry White baptised 18/12/1848 Lincoln. I have a marriage for HW marrying a Mary Lancaster 21/3/1848 with father Richard White, so maybe this is enough for this to be correct. The good news is Henry was a Dentist, so better to research than an Ag Lab. I think Henry and Mary may have had a son John bap. 29/9/1850, who may have died the following year. 10 years later a son Thomas Harry 18/11/1859-he was a Dental Surgeon, and appears to have married Rebecca, and on the 1911 census it states no children, so end of the line on that one. I don't know if Henry/Mary were still alive in 1911, but have had no luck with finding a 1911 census with them on to see how many children they had, or deaths for either of them. Maybe fresh eyes can help.
Regards.
