I cannot say as to what data I have in the McClurg files concerning Ola W. McClurg family. I have been on the McClurg case for over fifty years, amassed an archive of information and traced out many families from NY to California of which I have not found a living descendant. I have Heads of families who I have a profile on, but have not connected or identified to a McClurg family branch. I have also traced out know McClurg family members and recorded much history about them. I have researched living McClurgs who even lived in the same small town America that didn't know they were closely related to each other, and I am speaking of first cusins, Uncles, or another way...the same family. Most McClurgs are few and far between and think that they possibly could not be kin to anyother McClurg anywhere. Isolated. It;s difficult research. Therefore, as I say, I may have material here, but don't know who they connect to. My email address is on this message board.
If you can send me a Family Group Chart on Ola W. & wife I will be in a better position to assist.
