Margaret, I am still trying to unravel my Wilson's in county Cavan. All I know is that the Wilson families held farmland under Sir John Young in the south east section of county Cavan in the late 1700's to mid 1800's. Common given names being John, William, Robert and Thomas.
I do know that William Wilson, born about 1792 and uncle to my John Wilson, left for Ontario Canada (about 1845 to 1850) with his large family of children and his wife being Esther Coote or Cooteville, Co. Cavan. The oldest daughter Anne Jane married Stewart Hooey of Cavan. Other children named Matilda, John, Mary, William, Mathew, David, Thomas, Henry, Charles, Joseph, Sarah and Essy or Esther. The last few children were born in Ontario, Canada. The father and mother were still alive in 1860.
Also of interest are letters written between Anne Anderson...her married name and living in Kingscourt and Mt. Ida Dromore, County Down and our John Wilson living in Portland, Oregon USA. They were cousins but I don't know if she was a Wilson prior to marriage. Her daughter Jenny married a John Joseph Burnett. Also mentioned in one letter was the death of Rev. Winning and mentioned him as advisor and benefactor of all who needed his counsel and assistance.
Also of interest and maybe some help....A letter to my John Wilson from his cousin Matilda in Ontario, Canada tells of the Wilson history. Perhaps this will ring true with what you have knowledge of: "As to our origin, we are of Scottish descent and this is what my father heard from his father. When they came from Scotland they settled in County Longford. His Grandfather had three children all of which were drowned by falling into a well in his garden, after which he came to County Cavan and purchased a large tract of country, determined to leave the place of so much disaster and he was the first of that family that came to Co. Cavan and his name was John Wilson".
Sometime in the 1840's Sir William Young (Lord Lisgar) and son of Sir John Young mentioned above, built a fine stone schoolhouse in Bailieboro and my John Wilson went there for his education along with siblings, Robert, Thomas, William and Maria Jane. Birth years were 1826,1828, 1830, 1832 and 1837 respectively. Mother to these Wilson children was Joice or Jocelyn Wynne of Tubberdoney, Co. Louth.
Margaret, I hope something in this post will connect. Let me know what more you have. Thanks, Marilyn
