Thanks for your reply Ciderdrinker.
Have been working on the hunch that Henry and Thomas Senior were brothers – both families were in the habit of using two Christian names, John’s sons were Edward Henry and John Thomas.
Hadn’t realised the Guild of Shoemakers might have records like that, so will follow that line. Haven’t heard of Settlement Certificates – assume my best starting point there is the record office?
Family bible sadly doesn’t tell me where Margaret was buried, only that she died about “one oclock noon Feb 16”, haven’t found a record of her burial yet but will keep looking.
I did look at Butler wills before I knew about Margaret, but will revisit those with son’s names in mind.
On old familysearch I did find a possible family in Coleorton (mother Margaret, father William, sons Henry c. 1769 and Thomas c. 1771, amongst others, so plan to investigate them further.
There has been some paperwork done that suggests that Thomas Edward’s line stems from a Peter/Piers Butler from Ireland, via Shepshed, so possible that there’s no connection between the two lines, yet when we look at photos of living descendants of both lines, the similarities are uncanny!! Am also exploring the dna route, but would obviously want to back any findings up with records if at all possible.
Many thanks for your suggestions, you’ve given me lots of ideas.
