In some families, it's a tradition to honor a relative with a middle name in addition to the selected middle name. If you can't decide on names, at least agree on the first name, then you pick a middle name and he picks another middle name. One middle name may be the mother's maiden name to acknowledge the maternal family name. In the Catholic community, the second middle name is the given name of the child's godmother or godfather.
