When in doubt, match Wikipedia, as that's what we're all trained to search for.
First Lady or First Gentleman is the unofficial title used in some countries for the spouse of an elected head of state.
The title "First Lady" originated in the United States in 1849, when United States President Zachary Taylor called Dolley Madison "First Lady" at her state funeral while reciting a eulogy ...
*n.b. nice photo captioned: Bella Kocharyan, Laura Bush, Lyudmila Putina and Zorka Parvanova — first ladies of Armenia, the United States, Russia and Bulgaria in 2003.
SO perhaps on an international site such as Geni "disambiguation" efforts would lead to the *formal / informal* title being:
First Lady of the United States of America
IN the about me text.
As Jenna points out, "tree view" real estate is limited and tiny, and more text it harder, not easier, on searches and matches.
I would say, use the suffix field (NOT the middle name, never!) and put it First Lady. Save the full title for "profile" view in the "overview" tab.
First Name: Dolley
Middle Name: left blank
Maiden Name: Payne
Last Name: Madison
Suffix: First Lady
Display Name: Dolley Madison, First Lady
There's an occupation field that can be used:
Occupation First Lady of the United States of America
There's a nickname field that can be used for any alternate names, including her full name that includes her lst spouse, John Todd:
Nickname: Dolley Payne Todd Madison
What say others?
I think the problem *won't* be mixing them up from other countries such as Princess Grace of Monaco. I think the problem is incorrect merges with ladies of similar name in Colonial America, so our efforts should be focused to those who need *that* disambiguation help.
Hopefully no one is merging / managing in that area who doesn't realize we're talking about the US.
Me again... You will find I am a stickler for "do it the same way every time", sorry!
Some of the First Ladies have their maiden names spelled out (as in Erica's nickname example on Dolley above) while others have the maiden name in parenthesis, as per Geni default. Do we want to convert to nicknames on all for continuity? (In my humble opinion, this should really be Geni wide, not just on this project.)
