Search for ancestors of John Knox children: Hugh Knox, b. 1807, John Knox, b. 1810; Mary Anny Knox, b. 1812; William Knox, b. 1823; Robert Knox, b. 1827 in Killeyvalley Township, Parish Desrtoghil, County Derry-Londonderry County, Ireland. I would like to find ancestors still in Ireland that have the family genealogy of Knox families remaining in Ireland. I will share Knox genealogy of John Knox that emigrated to Philadelphia, Pennsylvania, USA in 1840's.
