Plural surname

Hi, Bews’, James’ Smiths’…
The Oxford Dictionary of English Grammar
possessive (n. & adj.) (A word or case) indicating possession or ownership.
The possessive case of nouns is also called the
GENITIVE
case, e.g. boy's, boys', Mary's, the Smiths'.

Pronouns in the possessive case are the series mine, yours, etc.; the corresponding determiners are my, your, etc. Some grammars include these determiners
under the label possessive pronouns; more traditional ones classify them as possessive adjectives.

The basic meaning of the verb have is sometimes described as possessive (e.g. We have a house) in contrast to its other meanings, especially the dynamic
ones such as have a bath, have dinner, have an operation, have a holiday, have fun.

I disagree with both of the previous responses.  The question is about plurals, not possessives, so I don't think you would use an apostrophe.  The second answer, Bewes, is probably just a typo -- I think what you're looking for is Bewses.  (I've never heard of this name, by the way.  But adding "es" works for Jones/Joneses.)  Or you could avoid the problem by saying something like "I went to visit the Bews family."

A related question:

Should it be "The Bews family" or "The Bews' family"?
Is either of the above equivalent to "The Bewses"?

Thanks.

The plural of Bews is Bewses, as Joneses is the plural of Jones, as in "keeping up with the Joneses".  There is one Bob Bews in this town.  There are two Bob Bewses in this town.

Bew's means that one Bew possesses something, as in Bob Bew's hat is in the ring, i.e., the hat of Bob Bew is in the ring.

Bewses means that more than one Bews possesses something, e.g., those are the Bewses' horses, i.e., the horses belong to the Bewses.

When referring to the Bewses, Bews' and Bews's mean nothing.
