Hello, William!
Not an answer to your question, but I would suggest you enclose the link in brackets (adding "Elmer-Elmore Genealogy" at the end of the URL and within the brackets, leaving a space between the end of the URL and the added text).
You could also add a similar link for the main URL for Boston Public Library (if you don't already have one on your free-space!).
It's sometimes good to remember that "less is more" - or is that "more is less?"
