Hi, Ragna

I've read that they didn't have to provide any identification when they got married. So, yes, people could lie about their father's names or give wrong information because they were mistaken.
I'm sure my Sarah Pope gave the wrong father's name on her marriage record and I curse her daily for it.

I just don't know if it was because she was mistaken, the clerk or minister made an error, of if she made it up out of whole cloth because she was illegitimate.
I sent away for the only birth that matched what I had in the census and it was for the wrong girl. Sarah's birth might not have been registered, for all I know.
Ever since finding out that my Barnett Barnett was Jewish, I wonder about the other families I can't track. For all I know, Sarah Pope was Sarah Popeskizw or Popesky or Popoff. (My head's about to pop off.)
It's good that you've trawled through the index pages on Ancestry; even though you didn't find him, at least you know for sure that he's not there.
If only you knew where he was born, you could inquire about baptismal records.
