Hiorns Elsie Frances T Rye 2b 2

The Rye Registration district spans parts of Kent and Sussex.

If you have her marriage cert that should have her father on it? You could then have a look on the census for 1901 or 1911 on one of the pay-per-view sites (ancestry, findmypast etc) to see herw ith her family.

If you need to order this certificate then go to http://www.gro.gov.uk/gro/content/certificates/ where it shoudl cost no more than £10 bp (some sites charge a whole lot more but this is the official site)

To find out more about reseaarching in the UK go to GENUKI www.genuki.org.uk and in particular lookup the pages for England and then Kent and Sussex to get more info on resources
