William John McIver and Ellen Doorish

William John or John William McIver b.1851, and Ellen Doorish b.1846 Doogary, County Tyrone, married in Derryvullan, Fermanagh on 28 Nov 1871. Believe Ellen Doorish may have emigrated to Boston in early 1870'sabout age 25, then resided in Lowell, MA.I see the Doorish name in the parish on the 1825-1835 Tithe Appointment. Also I see that there is a Doorish Point in Antrim. I would appreciate any help I could get on connections for Ellen Doorish or W.J. McIver. Thank you so much.
