You would also move the apostrophe after the "s" in "Robinsons," since here you are referring to a group or family with the same last name rather than just one person with that name. The house belongs to the "Robinsons" rather than the "Robinson."

An apostrophe is used to show possession: the house belongs to the Robinsons; therefore, it is the Robinsons's house. Our house (or ours - no apostrophe) is on Randolph Drive.

Unfortunately the Wiki spell checker doesn't know the correct usage either. Sigh.
