kith and kin

kith and kin idiom
Friends and family, as in Everyone was invited, kith and kin as well as distant acquaintances. This expression dates from the 1300s and originally meant “countrymen” (kith meant “one's native land”) and “family members.” It gradually took on the present looser sense.
