Hello there, my father Gordon Robert Soames was born in Dover in Kent (southern UK) and is one of six siblings. His father (my grandfather, now deceased), also called Gordon Robert Soames, ran away from his home in Dumfries, Scotland and married what was termed then a commoner called Gwen.
From what I understand my grandfather's family had family members living in the US and I do believe they owned/ran newspaper groups in the US.
Wish I knew more.
Regards
Tina Soames
