John Warfield 
John Warfield was born in 1674 in Middle Neck, Anne Arundel County. 
John Warfield, eldest son, lived upon "Warfield's Plains," the homestead of which still stands just opposite Baldwin Memorial Church, half-way between Waterbury and Indian Landing. "Warfield's Plains" extended up to Millersville, and "Warfield's Forest" was near Indian Landing.
In 1696, John married Ruth Gaither, oldest daughter of John Gaither, of South River.  Some genealogies give a marriage year as later as 1670.
The marriage took place on 16 Feb 1696 in All Hallows Parish, Anne Arundel County, Maryland. 
John Warfield, like his father, passed his life in developing his estate, but died in early manhood, 1718, before completing his surveys and transfers. 
He died in 1718 at Abington, Anne Arundel, Maryland.
