Jon, this is what I have pieced together so far from family records (written 1840) and the sparse genea evidence at present available from the main companies.
1671. Robert Brady married widow Mary Eastrup or Easthaugh.
They lived for a while at The Chauntry in Orford.
They moved to Iken Hall Farm.
The next family note is of their un-named son and their grandson William at Iken Hall Farm.
A Thomas Brady of Iken submitted claims for disbursements connected with his position of both churchwarden and overseer of the poor, over a sustained period between 1739 and 1756, and this might be Robert’s son/William’s or John’s father.
1731, Mary Brady died in Orford- poss. wife of the original Robert?
William took on an extra farm at Chillesford where he eventually moved to, farming successfully, as evidenced in newspaper accounts.
William married Ann Chaplin of Ipswich.
The BMD records at Chillesford are rather more in evidence than at Iken or Orford.
The children I can find from William & Anne’s union are: 1742 Thomas, b. 7 Jun., xnd 8Jun (named after grandfather possibly?); 1743 Thomas, 10 Feb; 1745 Sarah, Xnd 14 Feb; Robert b.1755.
1797 Robert married Mary Fuller.
1818 Robert died childless.
Returning to when the family was in Iken: John b c/a1726 ( who married Anne and Sarah), like William, is more likely to have been a grandson of Robert & Mary than a son. So there is still a missing generation, assuming there is a relationship at all. He could have been William’s brother or a cousin by a second son of Robert.
One thing I find a little disturbing is why there should have been a settlement order on John & Sarah and the kids in 1761, if John came from a moderately successful farming family.
As I’ve suggested previously, there is just a faint chance that despite the large number of steps from a possible common ancestor a matching link can be found through our autosomal DNA. I really don’t know how to find the matches, but if you do or someone else out there does, I would be pleased to send my auDNA results if you were in agreement.
If there is a match, this could take us a little closer to the relationship to Robert senior and his child or children. If this John was Robert’s son he was most likely born in Iken, although I’ve not yet found evidence of what year Robert & Mary removed to Iken from Orford.
I have also taken a FamilyTree yDNA 111 test, but there seem to be no English (or Scotch) Bradys to match to.
Mike
