I can help you with Elizabeth French; her maternal line at least. She is descended from Col. Thomas Becher of Sherkin (I can take it back further if you want)
He was born in 1640, and married Elizabeth Turner ( The daughter of Henry Turner and Dorothy Boyle. Elizabeth was born c1650 and died 1720). They married in 1665 and had 15 children, among them a daughter Elizabeth Becher, b.17.2.1670.
Elizabeth Becher married in 1697 Horatio Townshend/Townsend Captain of the Sloop "Lynne". Sadly Horatio died in 1697, leaving Elizabeth with an infant daughter Penelope. Elizabeth (Becher) Townsend married again in 1701 becoming the third wife of Bishop Dive Downes, bearing him a daughter Elizabeth Downes, who also married into the Baldwin family! Elizabeth herself must have died soon after (her will proved in 1707, because Bishop Dive Downes married a 4th wife and had two further children before he died in 1707.
Penelope Townsend married Philip French of Rath, Alderman of Cork (and I believe Mayor)[in 1740 Penelope becomes godmother of Susanna Evans Cox, at which point she is described as Widow of alderman French)They had issue including Elizabeth French who was born in 1713.
