Summary Question: If someone is leasing land from another person with the same last name and is presumably the one living next door, does that indicate they are related like father/son?
I have a marriage record from 1855 saying that my ggggrandfather Bartholomew Donovan married Isabella Mylrae in Lancashire and that Bartholomew was born in Ireland. The record also indicates that he was the son of a John Donovan.
I can't find him in the 1851 census, although there's one Bartholomew Donovan who is living in the area but married to someone that I can't find a record of death or original marriage. When I look at the Griffith's Valuation, there's one Bartholomew Donovan who leases his land from a John Donovan that is (presumably) living next door. Is that an indication that that John and Bartholomew are related?
