Diane, I note that you have tried to make contact with others (on other threads) who may be related to your Jenkins.
I'm afraid that you will still need to be more specific about which "Williams family" is yours. As you can appreciate, Williams is one of the most common surnames in Wales, so if you can give details of names, dates and places of birth, marriages, children, census information etc it will help anyone work out if they have a connection with your Williams.
Are you looking for help in tracing any of your family lines, or are you just trying to find "cousins"?
