It would be far less confusing if maiden names were always used for females. Believe it or not, this subject has been discussed a number of times at WikiTree.
Although WikiTree is wonderful and I'm so thankful Chris has made this site possible, the inconsistency in the way names are shown sometimes creates stumbling blocks. Displaying a woman's birth name every time would be very helpful. That way I'd know at a glance, for instance, that Sarah Williams was the daughter of John Williams and Sarah Sample was the dau-in-law. As it is, I see Sarah Williams and think she's the daughter when actually she's the dau-in-law and Sarah NewName is the daughter. If the two Sarah’s were in my close family line, there wouldn’t be so much confusion because I’d know them personally, but when they are distant kin it’s hard to keep them straight.
After decades of researching families, the consistent display in books, unpublished family histories, and over the internet has been:
Given name/s (Maiden Name) Married Name
Having said all this, the way names of females are shown has improved (in big part thanks to Jillaine :)) over the last year. Whether names are tweaked a bit more or not, WikiTree is still a great site and getting better all the time!
