Francisca and Ascension Sepulveda were sisters. Their father, Jose Antonio Andres Sepulveda (1803-1875) was landowner to
a large swath of Los Angeles County, including parts of today’s Orange County. They were descendants of the prominent Spanish
Mexican Sepúlveda family in the early days of Alta California in present day Southern California.

and Abigail Hathaway Dillingham. His brother was Stephen Hathaway Mott.
Maria Ascension “Chonita” Jacinta Sepulveda (February 15, 1844–December 1923). She was the daughter of Jose Antonio Andres
Sepulveda and Maria Francisca De Paula Avila. She was the mother of Georgiana Francisca Mott, Thomas Dillingham Mott, II
and three other children (total number of children was eleven, but only five reached maturity.)

Raho, Padre (Father) Blas – Blas Raho, C.M. (1806-1862) In 1856, he “was named pastor of Nuestra Senora de Los Angeles.
He began at once to redecorate the church. Once commentator noted that “the historic edifice, so long unchanged, was practically
rebuilt. The front adobe wall, which had become damaged by rains, was taken down and reconstructed of brick: some alterations
were made in the tower; and the interesting old tiled roof was replaced—to the intense regret of later and more appreciative
generations—whith modern, less durable shingles.”” Father Raho also aided in the marriage of Thomas Dillingham Mott and Ascension
Sepulveda by calling out to them, in front of the many guest at a christening party, and asking if they wished he would marry
them. Padre Raho, did this knowing that Sepulveda had already turned Mott down once before. Cited from Weber, Msgr. Francis
