First, no she is not Ivanka or any previous lady at ORMCH as far as I can tell. Lana is new and doesn’t match anyone to date before her.
Secondly, I have no clue what most of these ladies names are at other places and honestly don't care. That’s something I’m not planning on researching or going to every RMP to find out.
As this seems to be a concern for you, how about seeing her yourself and find out?
