FYI..Rev. Thomas Lowry(fath..rev joseph) did marry Florella Reid Lowry(fath. rev john Lowry)
oct 1833..Glenhoy,Clogher...seems he was in Barrie in 1849 according to church history.
they did lose a child presumably named after mother..there is a fam connection between rev joseph and rev john???.Also another rev john daughter..Helen married a William Lowry of
Crossgar..also another rev john daughter married a James Stuart and they headed to Ottawa.(Margaret)..Rev. John..1769-1846..his father was Archilbald Lowry..Donaghmore.co.Down. died 1813..No doubt your John and Jane will be connected..as seems the Rev's stuck together and
marrying of cousins seems likely.Cheers..
