I'm the gggranddaughter of John Truesdale and Mary Brown. I'm just starting to research my Irish roots and haven't gotten far yet, other than discovering that John and Mary were married in Ballymore, county Armagh in 1861 and that their fathers were William Truesdale and William Brown. I've found that William Brown was from Mullaghglass, no luck yet on William Truesdale. I'm wondering if we are related on the Truesdale side. Any idea about that?
