I don't have any info on the Darby farm.Walter Harley was my grandmother's uncle and we had lost tract of him. He apparently left SC between 1900 and 1910 with children and possible 2nd wife (or he may have remarried when he got to AL).Had finally found him and family in AL through Mark Davidson via this site (check out his postings).Mark has not responded to my last quirey, yet.I hope he is alright.
I would be interest in any info you have on this family, such as Mary E.'s obit.
I'm also looking for Walter's uncle John Harley. Thanks for contacting me.
