My exhusband is decended from her and I am researching for my kids. What I have found is that Anna Martha Boutcher's parents were Lady Jeanne Cleves and John Boutcher (Bouchierre) (1625-1679). Ive got her siblings as: John (1648-1704)Peter (1648-). I have gathered this from other people's family trees on ancestry.com and have no way of proving any of it. She is also listed with these relations in other genealogy message boards on the internet. Good luck!
