Hello Kay Have you searched the Community Trees section of the 'histfam' Familysearch' in the Welsh section? This is a link to a William Merrick which might fit your William? There is a 'ferch Meurig' in his ancestors? http://histfam.familysearch.org/getperson.php?personID=I208044&tree=Welsh Regards Michael and Penny Oram -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kay Hoover Has an extended genealogy been done on Meurig ap Llewlyn?  I have an immigrant, William Myrick/Merrick/etc, who is "supposed to be" a descendant of Meurig.  William was in America by the early 1630's..  I have a copy of a newspaper article stating the Massachusetts Meyrick's descended from Meurig came through the branch that went to Pembrokeshire from Gwynedd.  Article has no newspaper name or date.  Lewis Dwnn doesn't seem to have tracked my William's branch of the family.  Unfortunately the hundreds of Myrick postings on the internet quote each other verbatim and, according to Dwnn, those postings are not correct.
