Hi Richard,
I see this thread began 10 yrs. ago.
My 6th GGM, the widow of the Juan Bautista de Anza Expedition of 1775-1776, Maria Feliciana Arballo de Gutierrez (that later married my 6th GGF, Lopez & a Tenorio). She had 2 little girls w/her on that Expedition ... her eldest one later married a Juan Josef Sepulveda ... he is of those Sepulveda's from Sinaloa. If I recall correctly, his father and Grandfather were named Francisco Sepulveda.
You can look in Marie Northrop's Vol #1 book or go to Rootsweb you can pull them up; a daughter of JJS and Maria Thomasa Gutierrez was a Maria de los Dolores Sepulveda ... keep clicking on her husband from KY, his family one of them takes eventually leads you to the Scotsman, last name of Rolfe, that married the Indian Princess Nicketti, daughter of the Powhatan Chief. a daughter Cleopatra and her sister Pocahontas ... I'm not even kidding.
Btw: Feliciana's other daughter Maria Eustaquia married Jose Maria Dario Pico ... they were the parents of many, including both Governors Andres and Pio Pico.
Because of Feliciana, I am half related to the Pico and the Sepulveda families. After Maria Thomasa died, her husband married an Avila Y Osuna as his 2nd wife, but Thomasa did have at least one son I know of w/JJS.
She, ironically enough died in April 1798 and 4 records after her entry, on the same page was her stepfather, my 6th GGF, don Juan Francisco Lopez 6 Jan 1800.
Hope this helps you.
