Here are my comments on ILoI #127.

2: Antoinette de Lorraine - No conflicts found.

10: Elyse le Bref - There is a typo in the documentation.  The
name which is found in Colm's article is <Elyes>, not <Elyse>. I
have been unable to find any period citation for <Elyse>.  The
closest I've found is <Elise>, which is dated to 1419 in SMP s.n.
Eliza.

11: Gruffudd ap Owein - This conflicts with <Griffyn ap Owain>
(reg. 11/1998 via Trimaris); <Griffyn> and <Gruffudd> are
variants of each other, and they are not significantly different
in sound.

12: Gwydeon ap Arden - The given name was registered as recently as May 
2007 (<Arian verch Gwydion>, alternate name registered to <Arian Rose 
of Nairn>); it was registered without comment.  The documentation quoted 
Academy of Saint Gabriel Report #2216, which says:

"As you noted, <Gwydion> is the name of a character in the collection of
Welsh legends and mythology, the Mabinogion.  We know of only one instance
of this name used by a historical person in our period, recorded in 1308
[1]."

[1] Morgan, T.J. and Prys Morgan, _Welsh Surnames_ (Cardiff: University of
Wales Press, 1985), s.n. Boly.

14: Lasairfhíona inghean Aindrias - Following <inghean>, <Aindrias>
needs to be in the genitive case, i.e., <inghean Aindriasa>.  No
conflicts found with the name.

15: Líadain ní Dheirdre Chaomhánaigh - No conflicts found.

18: Renaut Lionett - This conflicts with Rainer Wulfgar (reg. 07/2005
via Drachenwald), "Azure, a chevron ermine between three griffins Or",
with a CD for changing the type of the secondaries.  If the submitter
is interested in pursuing permission to conflict, I can help him get
in touch with Rainer.
