For those who are not aware of Google Advanced Search, I find it the best way yet to not only find my way around the internet -- but to find my way around WikiTree itself.
I was just curious as to whether WikiTree had a profile for Joan of Arc. That certainly is not her Last Name at Birth, so how to find her? Simply went to
https://www.google.com/advanced_search
and entered "Joan of Arc" in the box for "exact word of phrase" and "wikitree in the first line for "all these words." Presto, Google found her file.
And I learned something. I had thought "Arc" was a place name added later in life. But apparently her father was Jacques d'Arc. So it really would be her LNAB. Thank you, WikiTree.
