I am looking for information on my great grandmother, Ysabel Velasquez b. 1864 in Mexico. She married ? Deras (may be Manuel). Her son Manuel was my grandfather, b. 1885. She also had sons Santiago and Hilario Velasquez Deras.
She traveled by ship from Mazatlan to San Francisco, CA, in 1904, with Hilario. Don't know if she stayed or returned to Mexico.
I am looking in the Durango area because the Deras name is common there and uncommon elsewhere.
