I also have questions about her daughter Lucy Bacon Hiles, she was born the same month as Susannah and George were married, couple with Bacon as a middle name makes me think George might not be the father.
This is the birth registration for Lucy. (Note - This surname also has various spellings)
ILES, LUCY mother: BARTHORPE
GRO Reference: 1876 S Quarter in EAST RETFORD Volume 07B Page 8
The name "Bacon" comes through the Hiles family line.
George Hiles (born 1850) - looks like his mother's maiden name was Bacon.
His birth rego is easy to find in the GRO index.
Isn't that nice and helpful, when surnames are used as second names in later generations.

Jane Bacon
Marriage by licence to William ILES
7 Feb 1836 West Burton (St Helen)
Both bride and groom made their mark X
Witnesses David Baines and Lucy Bacon
