They start ’em young in the Jay Ungar & Molly Mason Family Band. Will Merenda was born in January of last year and travels with his parents, Ruthy and Michael, who travel and perform with Ruthy’s father, Jay Ungar, and his music partner, Molly Mason. Don’t worry about following the lineage, just enjoy the acoustic foursome and their ukulele, banjo, fiddles, and vocal harmonies. The band performed Ungar’s “Ashokan Farewell’’ in Ken Burns’s PBS series “The Civil War.’’ 8 p.m. $20 suggested minimum donation.
