Julian Alviso born 1856 to 1858
Maureen,
To say that you know Julian was born in San Miguel is a little optimistic, he may or may not have been born in San Miguel. I have found for example for one individual when his children were born and it will say he was from a certain place such as La Estancia and in the birth of one of his other children it will say he was from Tlachichila and the birth of another child will say Monte de Duranes. Take that as a lead but until you find proof you can surmise or guess that he was born in San Miguel.
