There is a village of Bartley in England and there were lots of Bartleys living in and around Southampton England in the 1600's. One theory is that Bartley is a name+place name. "Lea" was the old English word for a grassy mound or place. (Gray's elegy:"The lowing herd winds slowly o'er the lea...")So "Bart of the lea."Others say it is a modification of Bartholomew, an idea with which I disagree.There were also some Bartleys in Ireland.One of the main routes for the Bartleys I've studied was from England to the colonies, then to Pennsylvania, then south to Virginia, North Carolina, South Carolina and Tennessee.During and after the Civil war, some Bartleys split for Texas, others for Missouri and Indiana.This is oversimplified, but hopefully of some interest.By the way, the village of Bartley has no Bartleys living there (at least not when I visited) and no Bartleys in the graveyard (there is no graveyard because the church is in the next village).
