Married name: Engelson?

After seeing That One’s latest Ae stunt brazenly flaunting her title for sales, it got me thinking about the name Engelson and how she never seemed to flash the name Engelson everywhere, like the title-as-name DoS.

I have found no evidence That One ever publicly used the married last name, Engelson, while married to Trevor.

They were married mid-2011 to mid-2013. She had about five acting credits during this time. There is some discussion that it was to retain her acting stage name. Let me ask some rhetorical questions about this:

1. If That One built an acting career with her birth last name, then why is she trying to go back to acting with a different name (the title of her 2nd/3rd husband)? She doesn't seem to care about her stage name now.
2. Why was Engelson never used as her “little family name” and to “share the same name” as her prior husband?
3. Why is That One using the married name of her 2nd/3rd husband so egregiously when she has prior mentioned “nearly losing her name” and her “identity"?

Is it because DoS is a royal title and Trevor’s name was just a regular last name, not conveying status?

Any alleged children should also be using their birth names, Mountbatten-Windsor, as American citizens living full time in the US.

• No evidence of legal name change with California courts
• No evidence of amended birth certificates (the alleged Archie as British could theoretically be updated but hasn’t, and the alleged Lillibet would not be allowed as born in the US)
• US passports cannot legally display royal titles

I also noticed that Tracy, Trevor‘s current wife and billionaire heiress, has proudly taken the last name, Engleson, as her Instagram displays her married name.
