I don't. She is the mother listed on a marriage certificate from Massachusetts in 1901. Which brings up more confusion. I just recently started working on the ancestors of my husband's Portuguese grandmother. Her parents were born in the Azores. I am not finding anything from the Azores. I have no prior experience with Portuguese genealogy, so my first hurdle is knowing what I'm looking at and how to enter it.
There are 2 marriages recorded for her son. On the first, she is listed as Maria Olympia; on the 2nd, Maria Olympia Da Gloria. The father is listed on the first as Manoel Jose S. (The son getting married is Alberto Silva Sequeira. https://www.wikitree.com/wiki/Sequeira-79
) On the 2nd, the father is listed as Alberto Sequeira. I'm guessing the latter is an error, unless it is a multiple name thing. Now with the son being Alberto Silva Sequeira, wouldn't Silva typically be the mother's last name? Is that helpful? They were clearly not having enough space on the form for multiple names.
The first marriage (1901) was to Maria Da Silva, daughter of Manoel Theodore Da S. and Angelina Augusta Silva. The 2nd marriage was recorded in 1925, to Maria C. Sousa Sousa, daughter of Joseph Sousa and Carolina Ennis. Both Albert and Maria were in their 40's. I have not found him in the census before 1920. In 1920, his wife is listed as Marie C. Sequeira. Same for the 1930 census. The birth records for children born in 1913 & 1914 list the mother as Carolina or Caroline Souza. The death cert. of a child born in 1920 lists the mother as Maria Souza. The first wife, Maria da Silva, is not in any record but that original marriage certificate. The parents are different, so they are not the same person. Best guess is she died, he remarried, but it wasn't officially recorded, so they remarried again later, to have it official. I don't expect this kind of obscurity in the 1900's. The 1700's, yes, but this is probably an example of the lack of tolerance and respect for immigrants of poor or no English in the governmental system.
