[Grammar] was denied his access

[Oceanlike]

Are both my sentences correct, using the proper noun (Erin)? I am unsure about using the apostrophe 's'.
I think it's correct when I use the pronoun.

- The club denied Erin access to its membership files.
OR The club denied Erin's access to its membership files.

- The club denied her access to its membership files.

 

[tedmc]

Access was denied to Erin. I think the possessive, "apostrophe s", is optional.

 

[tzfujimino]

So, the pattern in that context is deny somebody something or deny something to somebody.

 

[Tdol]

They're both correct, but I think the second implies that Erin had once had access to these files.

 

[teechar]

The club denied Erin's access to its membership files.

That doesn't work for me. If you want to use "Erin's", then consider changing the verb to something like "blocked".

 

[Oceanlike]

That doesn't work for me.".

Please help me to understand why it doesn't work for you.

- The club denied Erin access to its membership files.

Good.

OR The club denied Erin's access to its membership files.

Bad.

- The club denied her access to its membership files.

Good.

An apostrophe in Erin's would tell us something belongs to her. It would mean something is Erin's. Something is hers. It's a possessive.

So in your sentence, that would not make sense.

The pronoun her is not a pronoun for Erin's. It's a pronoun for Erin:

- Who was denied access? Erin was denied access. She was denied access.

- Whom did they deny access to? They denied access to Erin. They denied access to her.​
