Cool app! Q. When adding women (i.e. my wife) do I use her birth name or my last name?
You might want to state what version of GEDCOM this is compatible with. 5.5 is current. You may want to either say GEDCOM 5.5 or do some testing.
You're correct. Family.show is compatible with importing and exporting GEDCOM 5.5.
I can't seem to find the "Family" Schema. What Genealogy XML specification did you use?
