Rare occurrence of a second 2018/2019 stimulus check?

Ok so, I have a extremely weird dilemma. I received a stimulus check in April for myself, and my three dependents. I claimed head of household for 2018. I didn't file my 2019 taxes yet due to me just getting married. My wife has not filed her 2018/2019 taxes either, and so did not receive a check due to not filing. I just filed my 2019 taxes on July 15th, the last day. My question is, since she did NOT receive any money nor did she file, would she be eligible to receive a stimulus check now under her social security number? I read that its extremely rare but could possibly happen.
