George, it's me again.My John, b 1828 could be the same as yours.My Elizabeth A in the 1850 census is probably John's wife, as I have a copy of a birth record of a male child, born in Simsbury, CT in 1852, parents: John and Elizabeth Alexander.I do wish the Scots used more originality in assigning given names!
I have a marriage record for John Hutchinson andIsabella Alexander dated 1872 - Chicago, IL.They were in a household together as husband and wife in 1870, that is why I assumed an earlier marriage date.
I have a cluster of Hutchison/Hutchinsons, Alexanders and Fultons that moved around together and married each other.I believe they were related in Scotland and probably emigrated together.Do you have any Fultons?There is also a Louisa Alexander age 18 b Ireland in the Simsbury 1850 census.The other Alexanders show birthplace as Scotland in the census, but I don't believe that is correct.The same with the Fultons.The family members born in Ireland of Scottish ancestry did not consider themselves to be Irish.
The Canada association should not be ruled out as some of the children were born in Canada, indicating that the original emigration was to Canada, before entering the U S.Some of the group might have stayed there.
Ballingarry might be possible.These people moved around a lot!How far is Ballingarry from Dublin?
I will have to do some additional research in U S census records and look into the Canada connection, but I am at present preparing for a trip to Scotland.It looks like I should also consider a trip to Ireland in the future, after I find out more.
