Foster lived in
Wilmington,
Delaware until her marriage. Her family was part of the first group of
settlers on the eastern coast of
Maryland. She could be considered an
orphan since after her birth her father had remarried after her mother's death and moved to
Kentucky. She was considered as being part of "an
aristocratic family". The Claylands and Tomlinsons were some of the first families that settled in that area of Delaware. Stephen Foster is assumed to have gotten his "poetic temperament" from her. Her mother's family, the Claylands were
Episcopalians and had settled in America after leaving England in 1670. A biographer described the Claylands as
slaveholders, wealthy and active in political and social life during the
American Revolution. == Marriage and family life ==
