I would love to have the information you have on Alexander Madill from Lisbon, NY. My Great Grandfather was Alexander Madill son of Abel Madill (lived in Lisbon came from County Monaghan. My Grandfather's name was Alexander LeRoy Madill. I am most interested in David's brother Abel as this would be a new addition to my tree.My family and I found both Abels in St Lawrence County but we didn't know how to connect the two. Please email me @ email@example.com.
