Ugh, I've had that happen to me too!! Both Ancestry and familysearch sometimes give totally different results if you just switch the order of your search. Sometimes it's due to a misspelling or typo or nickname (Smit vs Smith or Jon vs John vs Jonathon or whatever) but sometimes it's.. I don't know.. a result of the phase of the moon?
Congrats on the success though!! WOOOT!!
