I have a paper back book, self printed I think, called "The History of Mayo, Maryland", by Caroline L. Britt Mullins. She covers much of what you have inquired about, but has a tendency to be sloppy in her scholarship. Example: she lists Thomas Linthicum's wife as Jane Baldwin Cotton. She has substituted one Jane, the compiler of a list of Maryland wills in the early 20th Century, with Jane no last name whom Thomas married.
Nevertheless, she has maps of properties and lists of residences which tie the people who owned land in Mayo in the period between 1650 or so to 1900. The point of land on the east side of Mayo is Sanders or Saunders Point.
Comparing maps I would say that the Saunders/Sanders place would be about that green patch labeled "Beverly Beach".
