Do any style guides recommend an apostrophe at the end for double possessors? (John and Jacks' house)

I am aware that the universally accepted style is to put an apostrophe-s at the end of the second possessor's name.

Example: Amy and Steve's car

My question is not whether that is the common rule; I know it is.

My question is whether anyone knows of a style guide, grammar, or other authority that condones writing this in the usual style of a plural possessor; that is, with an apostrophe on the end of the compound/plural owner's name:

John and Jacks' house

John Merrill, Stephen Arthur, Chuck Williams, and Donald Smiths' law firm

Thanks!

Solution 1:

I'm not going to do an exhaustive search of usage manuals -- and I don't think it's worth your while to either, because

John and Jacks' house

would mean the house belong to John and Jacks, where Jacks is the name of one person. (Perhaps it's a nickname.)

So... nice idea, but I don't think it will fly.

Solution 2:

Thanks for this question. I sometimes wonder and would sometimes want reliable references for some language styles. I saw an article Possessive with Two Nouns which says--

"The possessive case can be confusing, especially when two nouns are doing the possessing. Fortunately, The Chicago Manual of Style sheds light on this conundrum. [emphasis mine]

"Chicago says that when two nouns “possess” the same entity, only the second takes an apostrophe (‘):

my aunt and uncle’s house

Gilbert and Sullivan’s lolanthe

Minneapolis and Saint Paul’s transportation system"

I hope this answers your question.
