Earlier in November I wrote about Gregorio Diaz, a brother of my 2nd-great-grandmother Teresa Diaz. I requested a copy of Gregorio's death certificate from Los Angeles County. The death certificate listed his parents as Dolores Quijada and Jesus Diaz, and his occupation was taxi driver. Gregorio had been in Los Angeles County since the early part of 1955, living at 1172 1/2 Esperanza Street in the Boyle Heights neighborhood of LA. The informant on the certificate was Refugio Trujillo.
After a search of the US City Directory for Los Angeles from 1954, showing Mrs. Refugio Trujillo living with Pedro Trujillo in Los Angeles, I ran a search of the California, County Marriage records 1850-1952 on FamilySearch. Maria del Refugio A. Diaz married Pedro Trujillo on 13 June 1936 in Los Angeles. The parents on the marriage record were listed as Gregorio A. Diaz and Tomasa Arballo. Other searches found Tomasa de Diaz (with her maiden name spelled as Arvayo, Arvallo and Arballo) in the US Border Crossing records, with daughter Refugio Diaz in 1910 and 1911.
One crossing triggered another connection with the Diaz family - Tomasa's brother Jesus Arvayo. In May 1910, Manuel Diaz crossed the border at Naco, Arizona on his way to visit Jesus Arvayo. In the 1910 US Census, Jesus was hosting Jesus Diaz, son of Gregorio and Tomasa, at his home in Douglas, Arizona.
This gives a bit more insight into the family of Gregorio Diaz, and the overall connections between the Diaz family and the Arvayo family.
