Just started looking at the Calvert line. Ann Calvert, sister of Margaret was the second wife of Valentine Hollingsworth. "In America Since 1607" traces Hollingsworths and has the following on the Calvert wives. "John Calvert of Moote Some England married Grace ____. They emigrated prior to 1617 from Yorkshire to Lurgan Co Armagh, Ireland. Son: Thomas Calvert was born at Lygasory, near Lugan, Co Armagh, in 1617. He married 1647 Jane Glasford, dt of Hugh and Margaret Glasford. Children: (1)John Calvert, emigrated to Pa soon after the Hollingsworths and settled on a 300 acre tract in Delaware Co. (2) Ann Calvert, b. Killwarin, Ireland, 1650, m. Valentine Hollingsworth 1672 at Lurgan. She died 17 8mo. 1697 at Mewark M M, Delaware. (3) Margaret Calvert, m 1684 Thomas Hollingsworth I, she d 1 Aug 1687 Mewark M M. (4) Elizabeth." The book is well researched and has photocopies of original documents. Might be of interest if you can find it.
