Does Sinéad or Fionnabhar mean Jennifer

[Wildrover51]

    Once and for all what is the correct Irish word for Jenn/Jenny/Jennifer.
I've been to enough Gaelic names webs sites to make anyone go mad.
Yet I've come across the two following options more oft then not. "Sinéad" (also seems to mean either Janice, Janet, or Jane) and "Fionnabhar". Yet one site claims Jennifer is the Cornish version of King Arthur's wife Guenevere and Fionnabhar is the Irish equivalent. However, my wife was given a plaque long ago saying that Sinéad meant Jennifer. Which is it?
Ar son Dé!
