You sound right on the money here. I think his last name was MATTSSON. I have DOBs ranging from 1842 - 1845. The most accurate I think being Jan 5 1843.
I do not know the parents names or any siblings. Wanting to upgrade to world explorer but so busy with work have no time :o( if you could check for me that would be wonderful. Unsure when he left Sweden. earliest census I have is 1880 that lists him.
His name was spelled so many ways Nils, Nels, REDO RIDO.
Most frequent is Nils M Rido.
WE all have blonde straight hair yet everyone thought we were French as the family spelled it redeau and pronounced it redoe hahaha
thanks so much
