James was the son of Melchior Lavallin and Elizabeth Browne.[1][2] He was born in the 1690s and would have been at least 21 by 1720/1.[3]
He married Marie Francoise Lejeusne at the cathedral of St. Michel & St. Gudule in Brussels on 4th September 1718.[4] In May 1719 Countess D'Cunha wrote "Lady Faulconbridge is returned from Brussels : she gives a very good character of Jemmy Lavallin but a very great one of his wife, who is big with child. I hope the circumstance she is in will mollify my cousin Lavallin heart and be an inducement to him to forgive and be reconciled to his son and daughter. I beg you'll interpose your good offices and endeavour to make peace ; and by the character I hear of the young lady I dont doubt but by her discretion and prudence she'll make amends by her conduct for the want of a portion." In Irish document her name was variously given as Frances,[3] or Mary Frances.[5]
