Allen Sharp/Mary Thompson

Does any one have any information on this family. Allen would be one of the origial SHARP men who came to Cumberland County from Cornwallis in the early 1800's. I have found a family that I believe to be his in the 1851 census for New Brunswick. He is listed with wife Mary and 6 children - William, Samuel, Willard, Leban, Edward and Caswell. His birth would be approx 1797. I also found a marriage for a daughter Unity. I did find a Unity and a sister Jane in the 1851 census in Saint John.
