Les Lamborn from Chester Cty, PA must be related to me, too!! The Samuel Lamborn genealogy (published 1894?) is the same book I have, although its research only covers til mid-1800's. My great, great, greats are listed in there (Elizabeth Baily married to Ezra Lamborn, mid-1840's letter written from Ohio to Samuel Lamborn) - her name was incorrectly spelled since we own her sampler made in Chester Cty, PA in 1810 when she was 15 years old (born 1795). I'm part of the female line. My great-uncle (1892-1981) was named Lester Pierre Lamborn (Springfield, OH), and one of his sisters was my maternal grandmother. Some of my male Lamborn line still live in Ohio/IN, and are also interested in genealogy.
