Two middle names - and Christmas

When I was searching the Ireland, Civil Registration Indexes, 1845 - 1958 I came across two clan members from the 20th Century, one male and one female, who had distinctive middle names. They were both births in Ballymena. All I have are the dates of the births. Agnes McClurkin McIlhagga was born in the January to March quarter of 1909 and Robert Carroll McIlhagga was born in the July to September quarter of 1916. I have searched the 1901 and 1911 Irish Censuses for any clues to which families they come from and have drawn blanks. I have also posted queries on Carroll and McClurkin websites and blogs, again without success. I assume these middle names come from surnames of females who married into McIlhagga families, or they could be the surnames of either the mothers or grandmothers of Agnes and Robert. If anyone has any clues they can offer, please put a note on this blog or get in touch by sending me a message.

Over the Christmas period I'm off to see a Memorial Stone on which I've had my parents' names added to those of my grandparents. I'll publish a photograph when I return. Thank you to all who have sent Christmas greetings to the blog and all its readers. I wish you a happy and blessed time, especially if you are with your family. May 2012 bring more good genealogical discoveries!
