Freemason family history

(Garrett, IN. U.S.A.)

My Grandfather, Great Grandfather, and even farther back were Freemasons. My Grandmother was a member of the Eastern Star. They were proud of their affiliation and when they died, their headstones were engraved with the Masonic symbol. I would like to learn more about this organization and possibly even join. Is this possible?
