Please pardon the interruption? There is a lot of information found https://familysearch.org/
There are birthdates, christening dates, and even death dates that are missing from your tree. In 1900, Maria Guadalupe Castro was enumerated with 16 births and 11 were still living. Ten children shared that 1900 household and Octaviano (22 Mar 1876) registered for WWI Draft so he was the eleventh one. Antonio was born 2 May 1895 but was not counted in 1900. As a result, he may have been one of those who died prior to that census? Evidently there were two daughters christened Catharine (3 Nov 1878 and 8 Jun 1883)? The first one was not part of 1880 census so she may expired early, also? That leaves three children not found during initial research? I'm not related!
