It is very interesting to us all- hence the speculation. With the absence of wills and maybe land records,it is difficult to ascertain whether this branch of the family retained their money.
There seems to have been a move to Clare. The twins were born there and Priscilla died there.
If I recall the Bradys were from Clare.
I read that Elenor Fitgerald Gloster died at the Kilkee address. Perhaps a family connection.
I think more could be discovered perhaps with the twins birth certificates- the last known address and then investigate that death for Robert.
