Mystery Word (spelling might be wrong)- Marikinko - What language is it?

I overheard this lady repeatedly calling someone “Marikinko” sounding like I’m spelling it. It was not the child’s name. I have no idea what language it is or what it means. Any ideas?

If she was speaking Finnish it means “Mary too?”

Mari, a female name
-kin, “also, too”
-ko, interrogative suffix
