Thanks for contacting me. Yes, we are cousins indeed! My great-great-grandfather was John B. Keahey (Martin Elijah's older brother.) My grandmother was Dorothy Matilda Keahey, daughter of Charles Earl Keahey who was the son of John B. Keahey. I have been researching the Keahey family for a while now, and it seems that most of their history after William and Margaret MacKeachey is figured out, so I have been concentrating on solving the mystery of what they were doing before coming to the United States. Our family story always described the Keaheys as Scotch-Irish, too, and due to some information I have come across in my research, I wonder now if this is an accurate label. Do you know about the Keaheys and the church they founded with other Highland families in Wayne County, Mississippi? I have been trying to locate the book about that church, but it has proven elusive so far. I have been speaking with my dad, who still lives in Dallas, TX, to see if he can find out if the Keahey homestead (from the 1800's) is still standing in Erath County. Have you ever been to see it? I would love to hear anything else you know about the family.
