If you are searching for UK Sephardic families, The Knowles
Collection of some 40,000 names includes many Sephardic names.

I just wrote about this aspect of the collection (which of course
also features Ashkenazi names), in Tracing the Tribe - The Jewish
Genealogy Blog. Find that post here: http://tinyurl.com/cjhmol

The following are only the names under "A" - check the entire list
by scanning through the alphabet after downloading the Gedcom into
your favorite genealogy software program:

ABABI, ABADY, ABADI, ABAGUIL, ABECASIS/ABECASSIS, ABENATAR, ABENDANA,
ABISDID, ABOAB, ABOHBOT, ABUDACHAM, ADUTT, AFFRIAT/TT, AFLALO, AFRIGAN,
AGUILAR, AILION / ALION /AYALON / AYELION / AYLION, ALBERGA, ALERES,
ALETRINO, ALMOSNINO, ALOOF, ALVARENGA/ALBARENGA, ALVARES/Z,
ALVARES MENDES, AMAR, ANCONA, ANDRADE, ANDRADE DA COSTA, ANGEL,
ANIDJAR, ARBIB, AROBAS, ARROBAS, ASCOLI, ATTIAS, AZAR, AZEVEDO DE COHEN,
AZUELOS and AZULAY.

Hint: Scroll down through the alphabetical list, and see many more
Sephardic names both common and rare, with interesting name variants
that may provide additional clues. One hint for your search of the
Gedcom - after downloading into your software program - is to
substitute B for V, V for B, A for E, E for A, etc.
