Samuel was the son of William Cox and Hannah Ingham. Hannah's parents were John Ingham and Mary Whittaker. John and Mary had 10 children, Hannah being the ninth. Their fourth daughter Mary had an illegitimate son, John James Ingham.
John James Ingham and his wife, Elizabeth Ann Jackson, had two daughters. May was born on 20th May 1899 and Beryl was born on 9th September 1901 in Alliance Street Baxenden, Lancashire. My grandfather Samuel and Beryl were first cousins once removed and she was my second cousin once removed. Their father John James was landlord of the Bull Inn in Darwen.

At the age of 11 Beryl won the all England Step Dancing Title and later formed a clog dancing act with her sister May called the Two Violets.
In 1923, when they were performing in Castleford in West Yorkshire, she met George Formby. They were married on 13th September 1924 at Wigan Register Office. George's real name was George Hoy Booth, and his father James Booth was also a music hall artist and also used the name George Formby.
From all the biographies of George it is clear that Beryl was a very strong woman and was the driving force behind his career and really kept him under her thumb. She starred with him in some of his films and also decided which actresses could star in his films. She found many of them a threat and was very jealous.
