Couldn't quite give up on the RICHARDSONs.
Went back to my 2008 notes from the Morebattle Gateshaw session records to see if there might be a re-marriage of the widowed James, whose wife Margaret MABON had died in childbirth in 1812.
Although 8 years seems a little too long to wait to get a mother to his bairns, the family of James and Christian (OUTERSON) RICHARDSON came back into view. There's nothing on the 1820 Eckford marriage entry that indicates James was a widower, just that he was from Morebattle.
I'd never managed to find traces of them in Scottish censuses.
Spurred on by reminding myself that they had a son named Archibald Moffat RICHARDSON (Morebattle, 1832), I widened the net to the States.
An Archibald Moffat name is just too much of a coincidence given the Bermuda James' wife Mary MOFFATT, and her father Archibald MOFFATT.
Son Robert pops up in Winnebago Co., Wisconsin by 1850, stating he was born in Canada! Later censuses correct that back to Scotland, with 1900 adding an emigration date of 1841, and the 1860 having (mother assumed) Christy RICHARDSON, aged 64, born Scotland with the family.
His two subsequent remarriage indexes, between them, show his parents as James RICHARDSON and Christiana "OTTASUS" !
The mistranscriptions of OUTERSON abound, but that one takes the cake.
With the hint of Canada being somehow significant the net got wider.
Up popped son Andrew, with (assumed mother) Christian in the Quebec household in 1881.
Andrew thought he had emigrated in 1837.
One family tree has decided that Christian was born in Yorkshire (census records both indicated Scotland) - but as the Bermuda James married and had one child in Leeds, this may have been a bit of lingering family misinformation?
Another tree claims David for the James/Christian family but I haven't yet verified that one, other than yes, he's the right age, and of more than passing interest, is to be found in Oneida county, New York in one census - where Thomas of Bermuda settled. Well, the same county anyway, Thomas was at Trenton, David at Deerfield - which appear to be about 12 miles apart.
Just maybe, one day we'll find that John's Adam, born 1835 in New York, does belong to James of Morebattle after all, but the father not the son? He's only 3 years after Archibald Moffat RICHARDSON was born in Morebattle to Christian.
