Cornelia Hoyt Anzaldua

This week I've spent a lot of time investigating my family lines to the Anzaldua's of Cameron County, Texas.  In doing so I came across a newspaper article from 1916 detailing the suicide of Professor Luis Anzaldua.  Because my paternal grandmother is connected to a couple of Jose Luis Anzaldua's, I was drawn to investigate this death further.

I learned that Prof Luis Anzaldua was a musician.  He was married to Maria Hoyt, the daughter of John Ward Hoyt and Rafaela.  Luis and Maria lived with Maria's parents throughout their marriage.  As the years went by this would include their children.

According to the article Luis Anzaldua's body was identified by his brother in law, John B Hoyt. The census in the following years show that the children remained with Maria and Maria's mother, Rafaela.

One of Luis and Maria's children was, Cornelia Hoyt Anzaldua aka Nellie Hoyt and Cornelia Anzaldua Hoyt.  Miss Nellie is mentioned in some newspaper articles and Montys Monthly magazine.  What I've been able to piece together is that Miss Nellie had an angelic singing voice.  She would go on to be discovered by a Mrs Julia Montgomery.  When she performs a solo at a Rotary Club Luncheon in Brownsville, Texas the Rotary Club soon sponsors a trip for Miss Nellie to go to Houston with Mrs Montgomery to get a professional opinion regarding her talent.  By 1927 she is entered into a radio contest in Houston.

What I'm left with are the following questions:
1.  Am I related to this line of Anzaldua's? I'm unable to find who the parents of Professor Luis Anzaldua are.
2.  Marriage records for Maria's father John W Hoyt and Rafael Bistre is for 15 years after the birth of the Hoyt children.  Could it be that Rafael was previously married to a Mr Bistre and therefore the stepmother of the Hoyt children?
3.  Did Miss Nellie ever marry, continue her musical studies, acheive success under a stage name?
