Henry Ridgely was born between 1635-1639 in Staffordshire, England. He emigrated to Maryland in June 1659. He spent a brief period of time in Virginia, where he courted and married Elizabeth Howard
Contrary to some citations, Henry was NOT born in Tiverton, Devon, England, but in Staffordshire, England. The name RIDGELY does not occur in Devon, and this likely is confusion with his second wife Alice SKINNER, who was from Tiverton. 
First Marriage to Elizabeth Howard
Henry Ridgely married first Elizabeth Howard September 19, 1664. Elizabeth died between 1669 when her son Henry, Jr. was born, and about 1672 (the year Henry, Sr. married Alice Skinner).
2. Colonel Henry Ridgley II b. 31 Oct. 1669 Wald Ridge, Anne Arundel County, Maryland. m. Katherine GREENBERRY; d. 19 Mar. 1699[1700?], Anne Arundel County, Maryland.
As added circumstantial evidence as to the mother of Sarah and Henry, Jr., note that Sarah named her only daughter from her first marriage to John Brewer, Elizabeth (after her mother) and Henry, Jr. named his two daughters Ann (after his wife's mother) and Elizabeth (after his mother).
Henry's third marriage to Mary, widow of Mareen DUVALL was too late for her to be mother to any of his children.
Birth date unknown, died 1710.
