William JELLISON is my first cousin six times removed; we are related through his grandparents Benjamin and Agnes (PATTEN) JELLISON. William is one of fourteen children born to Major John and Elizabeth Tarbox (MILLIKEN) JELLISON on 5 September 1792 in Ellsworth, Maine. William married Julia Ann TISDALE 12 May 1721. William and Julia had ten children: Charles William, Edward Augustus, Caroline Leonard, Mellon, George Burbank, Zachariah, Webster, Julia Tisdale, John Dean, and Seth Tisdale. William was enumerated with his wife and children in the 1850 and 1860 censuses in Dedham and Ellsworth, Maine respectively. William died 23 July 1866 and is interred at Woodbine Cemetery in Ellsworth.
Due the commonness of his name, I cannot pinpoint him in most records (I have in my records over twelve with the same name living in the same general area). The 1800 through 1840 censuses do not list other family members, thus making it hard to determine the correct person. I will keep looking for more information on him. I am hoping when searching for more information on one of his siblings that I will find more information on him in that way. Stay tuned for more to come.
