Searching for the family of John Brewer was born in 1644 in Anne Arundel, Annapolis, Maryland, USA and passed away on April 5, 1690 in Brewerton, Annapolis, Maryland, USA. John Brewer marries Sarah Ridgely. I show that they had one child, Elizabeth Brewer.
This is the son of John Brewer and Sarah Ridgely, with a sister named Elizabeth. There were no sources - it was just floating out there on somebody's tree - but I thought it might be a starting place for you to look.
