I am trying to trace my husbands GG Grandfather Elario Domingo police officer and his family.
His son Viceinti Domingo born abt 1843 Bilbao Biscayne Spain married Mary Winn 1869 Liverpool.
Son Benjamin Domingo born 1875 Liverpool married Kathleen Willis 1899 Liverpool.
Son Vincent Bisenti born 1900 married Catherine Rietdyk 1924 Liverpool

Viceinti sailed with the Larrinaga line, Benjamin and Vincent were also sailors,

Any ideas of how I could start serching for information on the family history in Spain.
