The trouble is there is no other source
I have tried in vain for many years to find a William son of Robert LONG born between 1805 - 1810 in all the surrounding counties
The only time I could find this man was in the 1841 census, his marraige certificate, and his death notice.
Before 1841 he cannot be found anywhere - Willian LONG the colt breaker nor his dad Robert LONG the Carpenter

Thank you
Jill
