Jacob was born in Amsterdam, Holland in 1726. Then on 16 OCT 1765 he was Naturialized in Augusta Co., VA. Went thru my papers that Sara sent me and found that cousin Doug has so many "hand written" letters,
photo's of old news papers regarding this HARPER family, the horse LONGFELLOW, the OLD CHURCH that sat on the Harper land.
Jacob's son George Harper b. 1756. Jacob and Mary had several children.
These are the ones that Doug Harper has documented:

Doug Harper shows the dates and amounts of the land being sold off to the children of Jacob and Mary Conrad. He even has copies of micro film showing marriages, etc. Sara Harper sent me so much info about 4 years ago, and I still haven't been able to ansorb it all.
