danke, wie lautet die antwort auf frage 2? Thx!

The rule "y to i and add es" doesn't apply to family names

I agree fully with farfold.

P.S. Some names sound a little awkward when adding -s or -es.

Example: John Williams --> the Williams; Juan Palacios --> the Palacioses. In both case the plural is correct as indicated, but "the Williams family" or "the Palacios family" sounds a little less awkward.

In any case "the Rafferty family" sounds quite natural.

After "mature consideration"(?), no, after checking in CMS and OGS, I hereby hang down my head in shame and declare #1 null & void: family and first names ending in "y" form the plural by addition of "s" and not "ies".

eric, I'd still take exception to plural "the Williams" though, or is that a typo? I would certainly say "the Williamses" (just as one says "Keeping up with the Joneses") , though conceivably in writing (depending on how formal or elegant the context) I would look for ways of avoiding it.
