The Mormons have put a lot of microfilmed records online on their free site FamilySearch.org--I found at least a dozen new ancestors by searching old church records in Europe which they had microfilmed.
Someone wrote a book about my Grandmother’s paternal family line in the 1960s. The surname is Colvin. It goes back to the 1300s. It ends with my mom’s generation. It was kind of weird seeing her name in a book written by a complete stranger. My uncle sure got the big head when he found out that we are royalty!
