How did your family migrate to Sussex?

I'm trying to find patterns of migration. Many group migration patterns happen from 1000's of miles apart. Just because they're adjacent counties/states, doesn't guarentee a migrating pattern nor does it mean that certain groups didn't come from 100's or 1000's of miles away to reside in Sussex.
Here are a few examples:

1) Huguenot's from Palentine, Germany travels 1000's of miles away to settle in Beverly Manor, Virginia. On "who do you think you are?" they discussed a book written in German, that basically led many German's and others to believe that the Queen of England would transport them to America, and give them free land, ect.. Many of them landed in New York and couldn't pay for the passage they thought would be provided for them, and ended up being sold into servant bondage. Jost Hite was one of these. I don't know if he was from Palentine or not; but he was a hopeful immigrant from Germany. Jost became one of the first settlers and 'pied pipers' leading other families to Beverly Manor, after gaining his eventual freedom in New York.

2) 1720's-1750's Scotch-Irish that were recruited in person in Northern Ireland, families in mass travel to Beverly Manor and Borden's Grant to set up home in a new land.

3) Families recruited from Bucks County and Chester County, PA, by Joseph and Morgan Bryan joined the migration to Winchester, Beverly Manor and then many of them travel again another several hundred miles to North Carolina, and from there, hundreds of miles west to Kentucky, then again further west to Illinois, Ohio, ect..

These are just three examples. All of these examples included multiple families migrating from the same basic location to end up in the same new location. What I'd like to know is if there were similar migration patterns incoming to Sussex prior to 1800. Furthermore, I've found a possible pattern going west in the late 1700's and early 1800's.
