Thomas Mattingly immigrated with his family to Maryland in 1663-1664, and died shortly thereafter without making a will. His widow, Elizabeth, was given letters of administration and signed an executors bond on July 24, 1664.
An inventory of the family's good reveals that they had few possessions. Their livestock was a cow, a calf, and a heifer. They also had a still and most of the rest of the inventory comprised tools, personal clothing and housewares.
A local attorney, Walter Pake, who married the widow Elizabeth took care of the legal affairs of the Mattingly family. On 1 August 1665 he entered the rights of the immigrant Mattingly family to 300 acres of land. Having paid their own passage, each member of the family was entitled to 50 acres of land. A certificate was issued in May 1666 for 300 acres of land in Charles County, MD to be known as "Mattingly's Hope" and the patent for the tract was issued on 4 September 1666 made out to the two boys of the family, Thomas and Cezar.
