I have just come across your message and think we have a relation match. My family line is Boylan and am currently researching this line with the help from a contact in Ireland.
A basic line of the info I have is (working backwards) John Boylan son born 1908 son of Michael Boylan and Mary Ann McCarthy. Michael is the son of Anthony Boylan and Catherine Cramer. There were at least 6 other children. Including Anthony who married Ann McGlynn and had 10 children and Julia who married James Devanny and had 12 children. The maiden name you mention I have down as Lowry. It would be great to sort this family line out and any further info would be great. This is the first time I have used this board so not sure if you can send someone a PM as it would be useful to send you what I have. Hope to hear from you soon. Regards Sam
