Alzadie's most common variant seems to be Alzaida, and apparently 'alza ida' means 'round up' in Spanish, so maybe it's appeared as a name in the US via early Spanish ranch-owners or workers.
Lugarde is a small place in the Auvergne in
France, but I don't know if this has anything to do with your grandmother's name.
