My post is not directed at members' personal information. My post is specific to ancestry work.
If one looks at their TREE, Ancestry creates an index for each person in it. Each person is assigned ONE SINGLE SURNAME. It is this surname which is used by Ancestry's search feature. This surname is also found in a person's profile page. This is a critical flaw which has existed way too long. The system's search feature needs to be updated for a variety of reasons.
This flaw has led inconsistencies in Ancestry's database. Their database is built by members who upload and build out trees. Some people choose a maiden name, others use a particular married name, and others use both names in the surname field. There is NO field to differentiate the case of ADOPTION which has only increased when it comes to building out trees since scientific tools are now possible. What once applied to girls and children of known adoption now DNA is bringing to the forefront girls and by oys may carry one surname at birth legally and may carry a different surname which would apply to their inherited AKA biological lines. Because the surname switch may date back to earlier generations there is even a greater need to be able to have fields to isolate/filter a person using more than one surname per generation node.
