Send a message to the person who requested a photo of the grave monument of Abraham Walker with the following comment:
I think this Abraham Walker is my relative. I suppose he is Abraham Walker's father who came to Argentina and married Luisa Serrano. They had a son named Abraham Walker who married Cecilia Ramirez. They had 12 daughters, and one of them was Celina Sotera who married Agustin Casares Diehl. He is my great grandfather. Thank you and if you know something related to this, please let me know.
