Dear Veronica, You and I are 3rd cousins once removed! I'm so glad to see that someone else in the Deanda family is interested in documenting our ancestry!
I know the story of Candido and Maria "Boikes" quite well. Spanish speakers couldn't pronounce the name Burke very well so I always heard of her as Maria "Boikes". I can tell you the family folklore I know in a private e-mail message.However, here is what I have on your direct line:
My Deanda relatives (my grandmother's maiden name was Deanda) are from the Corpus Area. More specifically, they were from Jim Wells County (Nueces before 1910 and from San Patricio County in the late 1800s). Your greatgrandfather (Candido) was my greatgrandfather's (Tiburcio Deanda's)nephew (but during their lifetimes they passed as brothers).
Your great grandfather Candido was the son of my great grandfather's oldest brother (born 1877 and died in 1899) Candido [referred to by my grandmother as Candido "el viejo"] and Antonia Rodriguez. Two children were actually born to their marriage (they were married in 1896 at Corpus Christi Cathedral)---Candido and Abelina. When Candido died (he tamed/broke horses and was very good at it, unfortunately that's what killed him), his children and his wife Antonia lived with Candido's parents Gabriel Deanda and Teresa Gomez [my great great grandparents and your great great great grandparents]. They had the following children: Candido (el viejo), Jacoba, Manuela, Gabriel Jr. , Francisca, Anita, Tiburcio (my great grandfather), Anastacio, and Jose Andres). Circa 1901, Teresa died so Antonia took over raising the children. You can verify that they were all living together and that Antonia was the widowed daughter-in-law in the 1900 Census.
I would love to have a Deanda family reunion. It's too bad that Tio Dan (Daniel Deanda my great grandfather's half-brother) died in March of this year. He probably had a lof of geneological information on the Deandas (he was in his 90s), but I just never got a chance to go visit him to talk about it. We can talk about the rest of the story over e-mail.
