Tom and Rosemary have answered your question, but there's one additional wrinkle you should know about:
Unfortunately, if the woman's LNAB is "Unknown", she will not show up in the results when you search for her by her Current Last Name or an "Other Last Name."
People with LNAB of Unknown will appear in the Surnames list under their Current Last Name (but not any Other Last Names) if you sort the list, then select the option to "include people with current last name" in the search results, but aside from that they seem to be invisible to WikiTree Search.
