For instance, I see my great-grandfather is listed this way: "Nikolay Aleksandrovich Krylov formerly Крыло́в" and my great-uncle is listed as: "Алексе́й Aleksey Никола́евич Nikolaevich Krylov formerly Крыло́в." I entered my great grand-mother as: "Александра Викторовна Ляпунова" (her birth name) but maybe I should have included Roman script? And a number of my ancestors used French versions of their names when Romanizing them, others used different spellings of their names over time, depending on where they lived. Before I fill out my grandfather's tree I wanted to know how to proceed.
Is there a way to indicate variant name spellings?
