BROSIUS, Henry, came from Germany when quite young, with his mother and step-father, who settled in Philadelphia.  The latter both died of the yellow fever when it was so fatal there.

Henry married Mary Roberts, daughter of Isaac, of Bucks County, and settled in that neighborhood in 1793; but in 1805 they removed to West Fallowfield and purchased the farm now owned by Daniel Kent, who subsequently married on of the daughters.  Their children were Isaac, Benjamin, Mahlon, William, Harper, Mary Ann, Henry, Joseph, Abner, Nathan, Sarah, Charles, Agnes, Amos, and Ruth.  Of these, Mahlon married Mary Kent, 8,17,1820, and resided in Londonderry, afterwards in Upper Oxford.  Their children were Clarkson, Daniel K., Edwin (now of Kennett Square), Esther Ann, John Comly (physician, now of Cochranville), Joseph H., Ann Elizabeth, Lucretia M., Mary Jane, and Mahlon G.
