Are these still available? If so, I'd be very grateful if you'd send them. My interest is in Harriet Firth - perhaps the daughter of the John and Harriet of your certificates - who married Edward Tolson Gomersall (sometimes Gomersley) in 1859. At that time her father John was a sailor. Aside from the certificates, does any of this ring a bell with you? In any case, many thanks.
