There is my Benjamin Butler and then there are the other ones.
Mine was born about 1819 in New York State and is known to have lived in Michigan, Ontario, Iowa, and Missouri (and possibly a few other locations as well). There are other men of that same name who were of about the same age. I’m always encountering them when I’m looking through records on my Benjamin.
So I made a list of these other Benjamin Butlers and what I have about them–focusing on those who lived reasonably close to my Benjamin and were of about the same age.
I also made a note that there was a Benjamin Butler born in 1818 in New Hampshire who was eventually a governor of Massachusetts. His name comes up in a variety of newspaper searches due to his mention of his political activities.
All of that is done so that when I go back to work on my Benjamin after a break, I do not have to start from scratch.
