If the grantees in one instrument of conveyance are "John Smith and Mrs. John Smith," and the grantors in a succeeding instrument in the chain of title are "John Smith and Mary Smith," further evidence e.g. affidavit, recital, etc., should show that Mrs. John Smith is the same person as Mary Smith. The same conclusion should be reached if the grantees were "John Smith and Mary Smith," and the grantors in a succeeding instrument in the chain of title were "John Smith and Mrs. John Smith."
