This is in a cousin line I'm tracing and I have her spouse different in my Ancestry tree. So I was checking for documentation. What I have for Margaret, daughter of Richard Sherwood and his wife Margaret Baldwin is:
Name Margaret Sherwood
Birth 1593 London, Middlesex, England
Death 1670 Isle of Wight, Surry, Virginia, USA
Spouse Richard Williamson
From what I'm seeing, Margaret who married William Jarratt has gotten mixed up with Margaret Sherwood above. There is nothing in her About seciton to help clarify that.
Also, Lady Margaret Jane (Sherwood) Jarratt is my direct ancestor. I have her information from Wiki:

which indicates what I'm thinking, that the two Margarets have gotten confused on Geni, because it shows her parents as Edmund Sherwood and Jane (Thrale) Sherwood and she has an existing profile on Geni with the correct connections:
