My great grandmother and her two sons were all dissatisfied with how they were named by their parents. None of the births were officially registered at the time and there seem to have been no baptismal documents.
So, my great grandmother, born Martha ("Mattie") Harriet Logsdon, chose to become Martha Eugenie Logsdon. Her son, born Maurice Huntley, chose to become Glenn Maurice Huntley, called "Glenn." Her younger son, born Haydn Huntley, chose to be G. Haydn Huntley (in honor of his father, George Henry Huntley, but he only used the initial), called "Haydn."
I figured out how to handle Glenn Maurice: I put the Glenn in the Preferred Name slot and left Maurice as his first name.
What do I do with Martha Harriet/Eugenie and Haydn/G. Haydn?
