How stupid of Me!!!!
Henry Carrr was born about 1812 and married in Eastwood Notts on 19th July 1842
I have complete records of Henry (my direct line) from Henry on.
His marriage certificate notes hi father as Joseph Carr - Clerk.
I have a record of the existence of William and Joseph Jnr in a 'story' written by Henry's son - but he does not give dates or places etc except the very general note that William was a Clerk and Joseph a hotel keeper in Moira neither does he indicate if thy were older or younger than Henry.
I hope this limited information helps!!
Thank you Anne Ashford
