How Long Has Your Family Been in the Hills?

I was able to recently track my paternal grandmother's family line back to the 1740s. Her direct descendents left Antrim N. And in 1750 and arrived in Baltimore, then moved into the Carolinas. 80 years later they'd moved west (every generation or so) until they hit SE Ohio around 1830. Where we've stayed until now (we have a family cemetery plot with folks from the Civil war). So, Im just curious if anybody else knows anything about their family's immigration path.
