I'm looking for some opinions on which would be the most "etiquette appropriate" avenue here. While compiling our addresses for the guest list, I noticed what could be a problem. FI's cousin is professionally known as Dr. MaidenName, but FMIL told me that she socially goes by Mrs. MarriedName (she signs cards this way, FWIW).
My question is- to those of you who do/know someone who does goes by their maiden name legally/ professionally, but their married name socially; how do you prefer to have envelopes addressed?
