The plurals of last names are just like the plurals of most nouns. They typically get formed by adding -s. Except, that is, if the name already ends in s or z. Then the plural is formed by adding -es.
If the name ends in s, z, ch, or sh, you must add es. That means the Davis family becomes the Davises, the French family becomes the Frenches, the Hernandez family becomes the Hernandezes, and the Glaves family becomes the Glaveses.
Davis' is the possessive plural for the noun.... . Kelle Millett that would be for one Davis. “Pamela Davis' daughter lives here.” But if there's more than one Davis, it's Davises and to make that possessive you could add the apostrophe after.
Difficult family names
Remember the basic rule: don't try to make a plural with an apostrophe. Everyone is trying to keep up with the Joneses (add –es to form the plural). The form Jones's (with an apostrophe) refers to something that one of the Jones family members owns.
Both Lucas's and Lucas' are generally considered correct for the possessive form of the name Lucas, but style guides differ; Lucas's (adding 's) is often preferred for clarity and by some U.S. guides (like MLA), while Lucas' (just an apostrophe) is also common, especially in British English or for classical names, with both being acceptable for singular names ending in 's'.
To show possession using an apostrophe, add 's for individuals (“Smith's car”) and just the apostrophe after the s for plurals (“the Smiths' car,” “the Martinezes' dog”). By convention, names from classical mythology and the Bible ending in s show possession with the apostrophe only (“Jesus' teachings”).
It's Lopez's for singular possession (e.g., Lopez's car) and Lopezes' for plural possession (e.g., the Lopezes' house), but you can also use just an apostrophe for singular names ending in 's' or 'z' (e.g., Lopez' car) or rephrase to avoid the issue entirely by saying the Lopez family.
When used in words that end with an “s”, the “s” after the apostrophe may be dropped. Whilst both are correct, it is good practice to be consistent. For example: Thomas' (2019) research or Thomas's (2019) research.
When referring to the house that belongs to the Johnsons, this plural family name gets a possessive apostrophe added to the s, so that it becomes Johnsons'.)
As a corollary to that, a singular noun that ends in 's' could either attract the apostrophe alone or an apostrophe that is succeeded by 's'. This reinforces the appropriateness of: James'/James's wallet, Julius'/Julius's singlet and Thomas'/Thomas's girlfriend.
What's the possessive of a name ending in “s”? You normally form a possessive noun from a singular noun by adding an apostrophe and an “s,” but there's disagreement about how to form the possessive of a name like “James.” Most style guides recommend adding the apostrophe and “s” like normal: James's.
For names ending in s, you can either add an apostrophe + s, or just an apostrophe. The first option is more common. When pronouncing a possessive name, we add the sound /z/ to the end of the name.
The spelling Chris's, with an additional S after the apostrophe, is a more common way to write the possessive form of Chris. Most style guides, such as the Chicago Manual of Style, recommend that you use an apostrophe and an S to create the possessive form of a singular noun.

The Associated Press Stylebook recommends just an apostrophe: It's Tennessee Williams' best play. But most other authorities endorse 's: Williams's. Williams's means “belonging to Williams.” It is not the plural form of Williams.
Both Lucas's and Lucas' are generally considered correct for the possessive form of the name Lucas, but style guides differ; Lucas's (adding 's) is often preferred for clarity and by some U.S. guides (like MLA), while Lucas' (just an apostrophe) is also common, especially in British English or for classical names, with both being acceptable for singular names ending in 's'.
In English, if it ends in 's', then there is an apostrophe after the 's' and that's it. Having something like St. Brutus's is incorrect grammar.
“Louis'” and “Louis's” are the only two acceptable possessive forms of “Louis.” However, when it comes to choosing which you write with, it's entirely up to you and your personal preference. Make sure you stick to the same style throughout your writing, though.
When proper names end in s (whether singular or plural), add only an apostrophe. Use Lewis University's, the University's or Lewis' when showing possession in a sentence. Never use Lewis's. To indicate omitted letters, such as in contractions.
For decades, use '70s (with an apostrophe before the number for the missing "19") for contractions like "the '70s," and use 1970s (no apostrophe) for the full form or as an adjective (e.g., "1970s music"), while 70s (no apostrophe) is a common plural, but avoid 70's as it incorrectly suggests possession or pluralizes the number itself, not the decade.
It's not that “the Rodriguezes” is the most correct: it's the only correct way to make the plural of your last name. The other option you indicated is the possessive form of your last name, aka the Rodriguez's house.
