Have you ever heard of the Yeomanettes? Women in their teens and twenties were enlisted in the Navy as part of the military effort to support the First World War. Most served as stenographers or clerks, although a few were posted overseas. Their service likely provided the ground work for women's units during World War II - and women's roles in the modern military.
One of their bases was New London, Connecticut. Women staffed offices so that men could be deployed overseas. My own great-grandmother served her enlistment out at New London.
Don't forget to check military records for your female ancestors! Many are listed in rosters issued by the local Adjutant General's office. From there, you can order their service records. Who knows what you might find.
