I have one where the husband and wife had the same last name before marriage, but were unrelated. Threw me for a real loop there as I thought I couldn’t find her maiden name until I figured it out. Definitely a lot of ancestors changing the spelling of last names. Some I can’t tell if it was intentional, or just hard to distinguish between a’s and o’s on the old documents.
