Im a Lagan and from maghera..as far as i know there is at least two different Lagan families in the maghera area (bracareilly/lisnamuck areas) My grandfather was Patrick(Patsy)Lagan, he married twice, unfortunatly at the time of this post i cant remember the name of his 1st wife, however they had 4 children, 3 boys, seamus, michael and colm and a daughter maureen. He then married my grandmother Mary Mc Cusker and had 3 more sons, Francis, Gerard and Brendan.
I remeber my granny often talked of a felix. However she has sadly passed away so i will have 2 find out more from my father!
