Belated response. Thanks John for your message. Alas the genealogy programme I use - FTM - does not permit searching geographically. I know for sure that I have LUSKs in Auglaize and Allen Co.s in Ohio but can't select them on that basis. I have some LUSK/BLANK details and would really like to correspond directly with LUSKS currently researching and also any with Leatherwood connections as I have gaps there.
I've not been posting for a while because of changing houses. Since discovering my own family's direct DNA link with LUSK families in the US I am even more interested than I was before. Anyone reading this message can contact me if they have interests in the LUSK One-name study.
