Hi,
Nice to you meet you, shirt-tail cousin. My name is Rita Gervais. My Great-grandfather was Humphrey Shay (Shea), son of John & Ellen O'Connor Shea and grandson of Michael and Ellen Shea from Ireland. Your line is from John's brother James Shea. It's been a few years since I've done research on this line but I do have a photo of James Shea & his wife Ellen Enright and all the children. Was your grandfather also named James Arthur? I have a photo of him too. Email me directly at ritamg at gmail dot com.
