Hello ShaunJ
Thank you so much for all this fabulous information..
We did find a book written by Whimsical's Great Grandson Robert Breen, who informs that Thomas Henry Walker was born on 21/7/1851.
WHIMSICAL WALKER BIOGRAPHY
This is details of what Robert wrote:
WHIMSICAL WALKER
A clown of mystery
(Written by Robert Breen - great grandson of Whimsical Walker)
Mention the name "Whimsical Walker" and many different versions of who he was will be presented. This is the definitive outline:
Whimsical Walker toured the world 3 times, during the fourteen years he was with Hengler's Circus; and played 21 seasons in pantomime at the Drury Lane Theatre.
He came into the world on 21st July 1851, as Thomas Henry (Dawson) Walker - the son of the landlady of the inn The March of Intellect, in Hull, and Robert Stanley Walker, an advance man for Cooks' Circus.
I shall pass all this other information onto my relatives.
Once again many thanks.
