My 2x great grandfather (Jonsson-2135) was known both as Jonasson and Jonsson.( I'm sure I'm not getting two people mixed up because of the same birthdate, wife, etc). But because his daughter, my great grandmother, used the name Jonsson, her father's name went in as Jonsson, whereas it should have been Jonasson, which was his name at birth. But he was also sometimes known as Jonsson in the Swedish records, because this was the era when Sweden was officially adopting patronymics -- also, I believe he was illiterate, and when household records were collected he wouldn't have been too clear about spelling . What do I do?
