Although he was highly successful in his business, Ramsden does not appear to have been so successful with his marriage for his wife did not move with him when he opened larger premises in 1773. Sarah and their son John moved into a house owned by the Dollond family, but Sarah seems to have continued to assist Ramsden in his business.
