Leana,
Genealogy is concerned with 3 things: A name, a date, and a place. You have not provided any name. You just keep referring to 3 great grandma which does not help the reading audience help you.
No, the churches do not remember families from long ago. If you are Catholic, you see how the priests change at your local church. Same thing there. The priest at the church where my ancestors immigrated from on Sao Miguel....He's from Brazil. And he's younger. So he won't be remembering anyone from my family. Maybe someone in the village who is 80 or 90 today might remember some of my family. Maybe they were 6, 7, 8, when someone died in the 1930s. If you are asking for someone to remember a person born in 1850s or 1860s, it's quite unlikely.
Good luck!
