When a subject or an object appears as part of a compound structure, you may occasionally become confused. To test for the correct pronoun, mentally strip away all of the compound word group except the pronoun in question.
His stepfather and he is the subject of the verb had quarreled Test: he had quarreled (not him had quarreled).
Her father and me is the object of the preposition for. Test: for me (not for I).
When in doubt about the correct pronoun, some writers try to avoid making the choice by using a reflexive pronoun such as myself. Such evasions are nonstandard, even though they are used by some educated persons.
My husband and me is the indirect object of the verb gave.
