My John Boast, or his father or earlier ancestor, may have come over as a "younger son", as most of those early settlers did. Some of the wealthiest, most affluential ones started out with nothing but ties to the "elder son" of the family but little financially. And managed to manipulate themselves into such success over here. A great many of the sons who inherited their fathers' estates, were pretty stingy about sharing with their younger siblings. Yet some of the latter gained so much wealth, their more "fortunate" elder brothers had the gall to "put the bite on them". (G) I have read of so many of those "first sons" hogging all the estate and/or wealth and only tolerating their younger siblings' to scrape by financially. The younger sons usually ended up as (a) ministers, (b) clerks, and (c) (more often) tradesmen and/ or farmers. Over the generations, descendants of those younger children were mowed by time into a lower class and their families' beginnings forgotten.
I have noticed in some of my family lines that, about the time of and following our Revolution against Eng., the fathers had begun to give his younger children a break. :-)
