Hi, I have a scrap of information for you. I have a Michael Sheedy who m a Mary Healey [sp?] and lived in WI. This Mary may have been related to some Welsh's.
Someone was working with me on my Sheedy lines in Wi and told me about this other connection. Then the person stopped corresponding. He told me about a book that had information about my Sheedy's. But that $40 book had nothing. Some of the information that he had on my Sheedy's was not correct. Some was correct. So cannot be certain about the above.
