Hi Debra,
On her marriage cert she named her parents with the Santer last name, as far as we've researched there is no such family as David and Sarah Santer, but there was a David and Sarah Reilly with all the same details only differing in the surname. We assume they wouldn't have attended the wedding so weren't there to put their correct names. And an interesting point was that the two witnesses were F & B Reilly. We are assuming perhaps her sister Bertha.
