Noticed something while chasing a wabbit down a hole….

1. How common of a first name is "Zulma?"

1. There are 31 accounts of visitors to Obama's White House with the first name Zulma.

1. Lets say that Zulma is a common name, a lot of these listings are staying at the White House a very lengthy amount of hours. Anon wonders if somebody was changing their last name often, and if so… why? The White House is a busy place where time management is critical. 10 to 12 hour stays by guests, seems odd, especially if its within the "Residence." Even more so odd with a not so common first name.

Insights? Anybody else gone down this wabbit hole?
