The family history for Edward and Thomas Ellis indicates that their grandfather, Henry Ellis, was by birth a Welshman. He was a descendant of the Earl of Strambeau, whose family crest displayed a castle and two swords. In 1767, Henry Ellis left Wales for County Caven, Ireland. He married Margaret Mahan, a native of Donegal, Ireland. They were the parents of several children.


Henry Ellis and family immigrated to the United States and located at a colonist settlement on the Susquehanna River (Big Bend) in the State of Pennsylvania. During the American Revolution, the Ellis family remained loyal to the British Crown. About the year 1800, Henry Ellis and his three sons John, Allen, and David came to Canada as United Empire Loyalists. The family settled near Brantford, Ontario. Henry Ellis suggested that the new settlement be called Mount Pleasant after property owned by his family in Flintshire, Wales. The 200 acre Ellis farm was situated on Lot 7, east side of Mount Pleasant Road. The farm was the first to exist in the 4,000 acre tract of land, surveyed and laid out by Chief Joseph Brant. When the War of 1812 broke out, Henry Ellis and his sons volunteered their services to assist in repelling the invading foe. It was at this time that Margaret Ellis died after contracting camp fever. Henry Ellis died at Mount Pleasant in 1831 at the age of 86 years.
