I also like challenges.
I have nailed down most of the family in Ohio using FamilySearch.org - Most of the births were recorded at St. John's Episcopal Church in Cleveland so they probably lived on a nearby farm. The records are in the library at Western Reserve Historical Society.
The big challenge is finding the family in N. Ireland without the mother's name.
The 1901 Irish census is too late to pick up someone born in 1800-1815.
