This surname project is open to all families with the surnames Symes, Sims and other variant spellings. Please join our DNA study, focused mainly on Y-DNA, if you have an interest in genetic genealogy. Most people turn to DNA testing in an attempt to find related families when the paper trail backward in time seems to come to an end.

Alex Buchanan is the project administrator. Jim Sims is a former project administrator as of December 2025.
