how do i find out where my mother in Rainbow Girls was located in Georgia, columbus i think years ago? Grandmother was in the Eastern Star, she told me she was, but my mother denies this...

how do I find out about my mother's Rainbow Girls membership from years past or possibly still current status and my Grandmother's supposed membership in Eastern Star ?

THANK YOU in advance for help in this

(how do i find out if my Grandmother was in the Eastern Star like she told me she was?

she was married to a 33 degree Freemason of the Blue Lodge and her daughter was Rainbow Girls Faith level and her son was DeMolay Beau. Grandmother told me about her cousin also in Eastern Star. our family cemeteries and burial grounds are chock-full of Masonic and Easter Star, Demolary and Rainbow Girl tombstone symbols, inverted stars, obelisks, globes, columns,etc. also Oddfellows and Woodsmen and others. )
