Hi
Yes it would .The practice of women using their maiden name after marriage continued in England up to the early 1700's .In Scotland the practice continued until the mid 1850s and except for the census a woman would have kept her maiden name and it is used on children's baptisms etc.In Scotland deaths can still be looked up using the woman's maiden name.
So it's quite acceptable for these trees to have deaths for women under their maiden names.It actually makes them easier to find ,although i can see that it adds to the confusion about whether they are married or not.
Hope that helps

ps I don't suppose the woman concerned is a Ann Shropshire from West Bromwich?
