Hi Bean,
"Implied" may be the right term
15th/16th century Welsh gentlemen acquiring Arms sometimes used or incorporated Arms of an actual or supposed ancestor. Whether there is documentary evidence to support such a claim is another matter: in some cases there are genuine recorded genealogies and in others there are later constructs which owe more to the imagination than any hard evidence.
I note that a google search for "Llowden Hen" throws up a whole series of "Family Trees" claiming him as an ancestor but most of these seem to be copies of each other and do not quote sources. There is also reference to a "Tribe" of Llowden but this may be an 18th century construct. I am not an expert on the subject but this use of the term "tribe" seems to imply something similar to a Scottish Clan but may just mean "the extended family of" rather than a formal community.
If you are descended from Lewis Davies of Carmarthen the trick now would be to track
his ancestors to see if you can find the Llowden Hen connection.
Have fun
Maec
