bluefields family

I am the eldest child of a Nicaraguan mother and I am looking for family. My mother was from Bluefields. She was born Maria Inocente Gerlow on October 21, 1920. Her mother's name was Inocente Avellan, I think. Her father's name was Arturo Gerlow. He was Chilean and exported wood. He had ships. My grandmother was from Nicaragua. She had a brother Jaime who may have been a priest. I have pictures of many relatives. One of my great aunts may have been a nun. Any information would be appreciated. Thank you.
