We are searching for information on the families of Joseph Mederios b. 18 Jul 1849 on São Miguel Island, and his wife Mary Amelia Costa b. 20 Feb 1846. Her prayer book has an inscription referring to Ponta Garça. They were married in 1874 on São Miguel, and had at least five children there before emigrating to Hawaii, then Contra Costa County in California. The children were: Manuel James b. 18 Aug 1876, Joseph b. Sep 1880, Marie K. b. Jul 1883, Erma Elizabeth b. Jun 1884, and Annie D. b. Sep 1885. Mary's father was Joaquim Costa b. abt 1826, and she had a brother Manuel b. 5 Jan 1872 m. Mary Soares b. May 1873; and a sister Antonia (Antoinette Rita?).
We have extensive information about the family once they arrived in California, including many pictures. But we have had no luck tracking them back to the Azores. We are trying to decipher baptism and marriage records on microfilm, but find it very challenging, even though we understand Portuguese. Any assistance would be appreciated.
