Because of the cultural difference mentioned, I try to include the following notation in the public bulletin board for Smith women when I change her Current Last Name to whatever I expect to find on her gravestone.
"I do not have sources or additional information. Based solely on other names I see on this profile, I have changed her CurrentLastName to the one I expect she was using at the time of her death. I could be wrong, so please correct as necessary. The WikiTree database is huge, so we need to find acceptable ways to narrow our Smith search results. With this change, we can search for her by her LastNameAtBirth or her CurrentLastName and still find her. If she was married more than once, her other married names are in the OtherLastNames field and can also be searched. Ex: Abigail Amelia Betts formerly Smith aka Adams is profile Smith-4467, but can be searched as Abigail Betts and Abigail Adams, too. "
