So after doing some research it looks as if I improperly defined her as "British aristocracy" when that is not correct. She is in fact a titled Lady but not through the Royal bloodline or marriage into the Royal bloodline.
In truth, a manorial lordship is not an aristocratic title, but a form of landed property. The owner of a lordship of the manor can be described as [Personal Name], Lord/Lady of the Manor of [Placename], sometimes shortened to Lord or Lady.
In future press releases I will be sure to include the corrected information and I want to thank you for helping me sort this all out. I do honestly greatly appreciate it.
So in the mean time enjoy some extra photos of the lovely Lady Gemma Massey
