I am trying to find possible siblings of Joseph T. McGill and, ultimately, more information about his parents: Stephan McGill and Catherine McDonnell who came from Ireland. Joseph T. married Mary Frances Tierney and they had 8 children (one or two of which were born in Texas according to New Orleans census data. The rest, both younger and older, were born in New Orleans. I have good information on them. Speculating that there may have been relatives in Texas.
