I'm posting in case I can't get to you via email, but I'll try that again.
I’ve connected with a current James Ackerman, looking for info on his line. It appears we share James G. Ackerman as a great grandfather. He provided me with a little more info, but he’s stuck going back along the line too.
James G. Ackerman’s father was another James Ackerman, married to Elizabeth Wynn. I have James G. as being born in NY (somewhere) around September 11, 1868
Hope this helps. Thanks for any info you can give me.
