Catherine (aka Kathleen) Corrigan (born 1916) was my grandmother. I knew nothing of her working at a laundry, but when I saw the photo, I immediately recognised her. My only worry is that she looks a little old for the photo to have been taken in the '20s. I'd love to hear from you if you have found any more information. Even better, if you have any information on my grandfather (Edward Fahey), I would be very excited to hear from you.
