My grandmother, Jennie McAlonan is the daughter of Archie McAlonan, she born 18. According to a cousin, Malachy McAlonan, Archibald, b. about 1815 had a son Archibald, b. 1847. He m. 1871 Susan and we believe her to be a Laverty.
He had children Michael, Pat, Helen Mary James and Jennie, my grandmother, most born in Dunloy one perhaps in Armoy where I understand another branch of the McAlonan family lived.
Not sure how this connects with your line. Also, there is a small place called Killagan right near Dunloy that my grandmother's family were supposed to live. Anything strike a bell?
