Thanks to Gale, John and Hans for your answer to my message.
Hans, it is very probable that the name that I look for is Eter, because in
all the papers that I have, death, cemetery and birth of the children,
appear thus writing.
I made a search in the "family search" website and I found people with that
name, emigrants of Germany, been born more or less in those dates, and
although I did not find enything that was related to my ggmother, I found
some "Eter" born in Hannover.
In my documents the only mention is that she was from Germany, but my
grandfather told me that she was from Hannover. I know that her husband, was
from Oldenburg, maybe she was from the same region. I don't know how to
proceed. The information that I have from Peru is the only one, and now I
live in Spain.
Thanks to all of you for your help, and I will tell you more if I discover
something new.
Pedro
I think aslo area in New York USA called PERU.
