Hi, I'm trying to locate information about my great grandfather Carlos R. Gonzalez, who was born, I believe in Madrid circa 1869. I have limited information about how he arrived here in the US, only that he came here the following year around 1870. I tried to do a search here on ancestry.com but was waylaid when asked for departure city and ship name. Does anyone know how I can obtain that information or another way I can search for my great grandfather? Any suggestions offered will be greatly appreciated. Thank you in advance.
