I hope you might consider using the following in your Friends blog, or pass along to others:
I am a published author of four nonfiction books (two more pending with publishers), and am now working on the first-ever biography of Dr. Jonathan Letterman, the Canonsburg native who became "the father of battlefield medicine" in the Civil War when he invented the ambulance system, among other innovations.
I'm looking for people/sources/information about the Letterman (Leatherman) family in Canonsburg in 1800-1850. JL's father, Dr. Jonathan Letterman, was an early civic leader in Canonsburg. I have a great deal about Jonathan and the Civil War, but relatively little on his childhood. (He was born in 1824 in Canonsburg.) Often smaller communities have "resident historians" and I'd welcome the opportunity to visit with someone who's familiar with early Canonsburg life and/or the Lettermans.
Thank you in advance for your consideration.
