Manuel Sousa (1845 - 1910) and Blanche (Marshall) Sousa (1855 - 1890), my GG grandparents, emigrated from Sao Miguel, Azores entering Boston Harbor, Massachusetts on 15 September 1881. They _MAY_ have been passengers on the bark "Sarah".

I am trying to trace the parish/town in the Azores from which my GG grandparents emigrated. All requests for information from the islands require the name of the parish/town of the people.

Does any one have a way of tracing parish/town information?
