Hi there!,
I've recently started doing some family history research on the Welby/Whelby name in Wales. Being in Australia I am completely lost when trying to work out all the different
"...shires" across England and Wales, so please forgive me if I have posted in the wrong area.

The family lines I am trying to chase all so far seem to come from the Pembrokeshire area, so I thought I would start here. I have however got stuck and cannot find information that allows me to go back further with any degree of confidence.
I have got as far as Mr William Morgan Welby b:abt 1819-1825 in Tenby, Pembrokeshire Wales (date keeps changing depending on which census he was filling out at the time!) he died about 1896 at the age of 77. (Two death indexes found, for a William Welby, not sure exactly which one he is!) Can't locate an exact birth index or reference to clarify age.
I have reference to him marrying a Martha Lewis (nee George) in 1855 again in Pembrokeshire. They went on to have 5 children together (plus two from Martha previous relationship).
I have Williams parents listed as Jane Morgan and Richard John Welby. (not confident they are the right couple as Richard John Welby is listed as being born in Kent England, (I am guessing this is a long walk! but alas cannot find any other reference.)
My husband is a descendant of William (we think!) William would be 3x GG Grandfather.
Any help or pointers where to locate further information would be appreciated. (I have a subscription to ancestry and have exhausted, Census data, BDM indexes, etc on here)
Kind Regards
Sharon
