This question already has an answer here:
For the plural possessive of a surname, would you concur that these are correct?
the Rogerses' house (surname is 'Rogers') or should it be "the Rogers' house" for the plural possessive because 'Rogerses' is awkward?
the Hastingses' property (surname is 'Hastings') or should it be "the Hastings' property"for the plural possessive because 'Hastingses' is awkward?
Correct to these four?
the Williamses' property line
the Kennedys' house
the Joneses' dog
the Goronskys' pool
And lastly, would the following be a possessive or descriptive? 1 or 2?
(1) the Stevenses' family tree
(2) the Stevens family tree
A big and appreciative thanks.
