Theatrical family - missing

[Lorraine Karen]

Hello Genealogists Forum

We have a theatrical family that was previously unknown to us!

Please help find Eliza Priscilla Thrasher born 1869 London after 1891
her daughter is Violet Alice Louise Jezard, born out of wedlock

Please help find Violet Alice Louise Jezard born 1890 London after 1901
Violet is given false parents on her birth certificate and baptism and hidden from the 1891 census - why?
Violet is born in Finborough Road and Sacillia Lovell registered at that address is not found on any other records - why?
The Thrasher family change their name when Violet is born, to hide her birth or hiding from debts?

Horace Thrasher born 1893, later known as Horace Courtenay
Horace is given false parents on his birth certificate and baptism, why
Mother Alice Thrasher born 1871 London later known as Grace Courtenay
Grace married step-father Herbert Solomon in 1901
Horace and Violet are sent to a girls boarding school in Southend in 1901, why
Being age 7 and illegitimate his father could remove him from his mother, did the mother move him and give them alternative names to hide them or the father move him to give him a better start in life
Grace is living in a boarding house in Kensington living on own means in 1901 the family rumour that Horace was the son of an Earl or an illustrious member of the aristocracy, a person of considerable note.
The Thrasher family change their name when Horace is born, to hide his birth or hiding from debts.

Please help find Edward Leslie Court born 1905 London after 1926
Mother Ruby/Ruth Court (maiden names Ruth/Ruby Thrasher/Jezard), father Albert Edward Court Chief Of Staff London Coliseum
Ruth emigrated to America in 1905/1912 and had a common law marriage with also married Edward Warren Congdon a theatre booking manager, she was herself an actress/dancer and died in San Fransisco in 1968
Albert died in 1923
Edward emigrated to Canada in 1926

Eliza, Alice and Ruth's sister Louisa married Percy Atkins a theatrical business manager at the London Lyceum, The Globe (we have a silver bowl with The Globe Club engraved underneath, the bowl looking like the beautiful domed theatre ceiling) and other London theatres.

The sisters parents are Robert Thrasher and Priscilla May Pope, who were also probably not married as no marriage certificate can be found - but according to the Charles Booth survey the Thrasher family live in wealthy, respectable areas of London.

The Thrasher family are known as Torplow/Triplow, Jezard and Courtenay.

Thank you for your help!
