Lori, It looks like what you found makes it a great possiblity that the H. B. Penington in the 1850 census is the Hyland B. Penington, who was born 5 March 1777, son of Robert and Mary Penington and that the William Penington living next door was his son. I have Hyland B. Penington marrying Edith Henderickson 1 April 1799 by Jeremiah Cosden, dau of Augustine Hendrickson ( -1800) and Rosamond ( -1804), so that Elizabeth mentioned in the census would I guess be his second (or later) wife; (as you mentioned) Elizabeth Rothwell, who he married in 1816. I am sure you thought of all this. William would be the son of Hyland and Elizabeth. Have you checked the 1860 and 1840 censuses? I wonder of Mary J., William's wife (I assume) was the daughter of William J. Hayes with whom they are living? I would be interested in what sort of merchant H B Penington was. I appears that he had some sort of concern at Cecil Crossrords, Maryland [now Ceciltown] (South east corner), which he rented from Richard Savin. It was lat er sold to him (Penington), I believe, after Savin's death in 1800 (sale was in 1804). Vol XXV 1804-1805 {Land Record ABSTRACT} p. 98 Doctor Richard Savin, son of Augustine of CC, to Hyland Biddle Pennington in cons. $450 currency of USA, lying at Cecil Cross Roads in Sassafrass Neck at corner of Hyland B.'s store, boarding on the road leading to Bohemia Ferry toward Warwick near house now in tenure of John Loftis, willed by Richard Savin, dec. to nephew. Ip John Cox; Jno. Savin. S/Richard Savin; Rec. 27 May 1804 Any information about Mary Penington, sister of Hyland B. Penington, who married Richard Savin, son of Thomas Savin and Ann of Cecil County, Maryland would be appreciated. Or anything about any Savin or Benson of that area as well. Does anyone have the Cecil County, Maryland Peningtons in any kind of order? Mary the wife of Robert Penington who were the father and mother of Hyland, was possibly a Biddle, but have no proof as of yet. I do have some information about the Biddles as well, but unable to connect them directly. Will Brown
