Any information on the Wife of John Jacob (b. c1686; d. 12 May 1740 of Anne Arundel County MD)?

Her name was Mary Swanson (Swanston), daughter of Francis Swanston and Susanna Plummer of MD. She was my 7th great grandmother. I am having difficulty finding information about her father Francis. Also, who were Susanna's parents? Thomas and Elizabeth (Smith) Plummer?

Thanks,
Marty
