Hi Joanne, I'll try sending Ancestry e-mail to those Family Tree researchers who have Thomas Oliver ELDER information posted on their webpages. Sometimes they have posted photos. They also can "invite" someone with regular e-mail to view Family Tree webpages.
Recently I completed my DAR Membership application, approved #833222, for Revolutionary War Soldier, Robert ELDER, born 1730 near Perth, Scotland, died 1807 in Franklin County PA.
So when my brother's Y-DNA matched other PA kits, I was sure I was in the correct "FRANKLIN CO PA" family, which displays different Y-DNA than the "PETER ELDER" descendants.
We were surprised when we discovered several different major lines of ELDER families, now posted separately on our ELDER DNA webpages, see "Y-DNA Results" charts at http://www.familytreedna.com/public/Elderhttp://www.familytreedna.com/public/Elder
