Many Lisle families were living in America at the time of the Revolution. Many of legends about arriving in America with siblings and most of those sibling relationships have never been established.

A significant goal of this project is to establish what relationships, if any, exist between the early Lisle/etc. families. It is known that several members of these families participated in the Scottish rebellions against the English in the 1700s. Consequently, many who arrived before the Revolution were careful not to identify their family origins.

Some Lisle/etc. families changed their name when leaving the UK. So a minor goal is to identify people with other surnames who are biologically Lisle.
