You wrote to my sister Pearl concerning the Speck family tree. She called me and sent a copy of your info to me, which I received today. The only family tree study, to my knowledge, was done by my dad's brother, Richard. He did the Lederer's side and a little Speck, Hope, & Carman, all related. He only went back to George T Speck.
Pearl doesn't have Internet service so can only write. Pearl has a better memory than I, but probably won't be able to help much. Just in case this is her phone number: 716-693-0545
I also don't have a membership to Ancestory.com, but put some info on the site.
