Rosary Broxay Cooper, daughter of a Baptist minister, was born in 1913 and grew up in Eatonville, FL, one of the oldest Black towns in America. She graduated from the all-Black Florida Normal School with certification as a children’s nurse.

Hired to care for the children of the Merrill family, she traveled with them to New England, where the family owned a resort in Maine about 15 minutes from Portsmouth. It was there, in 1938, that she met and married Owen Finnigan Cooper and moved to Portsmouth. They lived with his mother and sister.
