Plural surname

Either is acceptable.

Could you give a bit more explanation about what you mean here, Anon?

Do you believe the same pattern is true for the surname Jacobs?  Is the plural Jacobses or Jacobss (the double ss for a plural spelling popped up when I Googled it).

Seriously?  Do you know of any word in the language that ends in S in which we make it a plural by adding another s?

The only ones I saw were Jacobs's.

Tim Jacobs's house is the last one on the street.

Like any other word that ends in ch, add "es."

Geryches.
