Dan, O'Gorman says "Hugh Parral owned 466 acres adjoining the land of John Calvert. He may have married John's daughter Ann Calvert, as his will probated October 5, 1748, mentions his wife Ann, his sons Daniel, Joseph and John; his kinsmen John Bruce, his son Edward, daughter Christiana "not yet of age," and his cousin (which frequently meant "nephew"), Robert Calvert. Later, it says "Issue of Richard and Sarah (......) Calvert: i. John Calvert b. abt. 1765; d. abt. Nove., 1838; m. Jan. 21, 1821, Anne Parrell. No issue. Will dated Apr. 1838; proved 3rd day Dec., 1838. He bequeaths to Sarah Parrill, widow of Joseph Parrill, dec'd, and her three single daughters, viz: Eleanor, Sarah and Mary Y. Parrill, all his real and personal estate when and wheresoever it be found: viz: Thirty-one acres and a half of land, lying in Frederick County joining Arthur Carter and others, also some revolutionary claims, and furniture of all descriptions to them and their heirs forever." Also: John Calvert who died in 1738 and his wife Jane had children Rebecca and Ann, Richard, Robert, Isaiah. "Ann b. prob. abt. 1725; perhaps m. Hugh Parrell" Hope that helps. Peggy
