I would like to delete all text after the 2nd comma to the left of strings in a dataframe that include "County, Texas". For example,

**Before:**

1. "Jack Smith, Bank, Wilber, Lincoln County, Texas"
2. "Jack Smith, Bank, Credit, Bank, Wilber, Lincoln County, Texas"
3. "Jack Smith, Bank, **Union**, Credit, Bank, Wilber, Lincoln County, Texas, Branch, Landing, Services"
4. "Jack Smith, Bank, Credit, Bank, Wilber, Branch, Landing, Services"

**After:**

1. "Jack Smith, Bank"
2. "Jack Smith, Bank"
3. "Jack Smith, Bank, **Union**"
4. "Jack Smith, Bank, Credit, Bank, Wilber, Branch, Landing, Services"

Thank you for your help!
