The Freeholder Records for Ulster which date from the late 1700s to about 1830s show only a few Ovens families and these are all listed on the same page in 1796:

Thank you for providing the link. I don’t believe that I’ve seen it before, or, at least I didn’t retain the material.
Included in the list was
1796 Wm Ovens, abode place - Drumavel(?). Devonish Parish(?)
I looked at another Anc*try tree, this time at “N’s” tree. “N” states James Ovens’ parents were William Ovens and Anne Drinnan.
A source in the tree
Griffith’s Valuation Ireland, 1848-1864. (A number of years after 1796, but…)
William Ovens, Drumanure, Devenish, Fermanagh
Could Drumanure actually be Drumavel?

“N” states William was born in Tulnagoan. I will check a map for their locations.

https://www.igp-web.com/IGPArchives/ire/fermanagh/churches/1803-1814-up-inismacsaintbap.htmlMy John’s date of birth varies. In 1850, he was born c1814. In other documents, he stated he was born c1809. (1881 census - born c1811.) I don’t believe I know his birth month. Anyway, I will keep researching James Ovens and his possible parents, William Ovens and Anne Drinnan. Of course, I will also try to contact “M”.
