How do you write the possessive form of a name that ends in "s"?

Question

I'm wondering how to make "Motts" possessive. Is it Motts'? Motts's doesn't seem right to me.

Answer 1

take jesus for example:

jesus' would be the same as if you were to say tom's, d**k's, or harry's

:):):)

Answer 2

Yes, you add the apostrophe after the s, so Motts' is correct.

Answer 3

According to William Strunk's 'Elements of Style', he recommends you add an 's.

The only exceptions to this rule is when using ancient proper names ending in -es or -is.
