People   (Re-unions, trace old friends and relatives.)

I traced your Israel Norman back (on one Census he is Isaac Norman) but if you look at the family it seems that the name of Isaac changes to Israel:

John Knowles b1857 the eldest son of John Knowles and Martha (so he was the brother of Thomas Knowles MP)

Married 1853 to Jane Almond at St. Peter & St. Paul Ormskirk, Jane was born in Lathom (Janes father was an engineer)

John died 15.09.1860 and we find his widow in the 1861 Census at Crawshaw Cross, Warrington Road, Ince with:
Robert 6
John 4
Martha 3
Thomas 1

Jane died in 1862

1871 Census - John 14 - Pupil at Knutsford

also in the 1871 Census we find:
Robert 16 - Nephew
Martha 13 Niece
Thomas 11 - Nephew
living with their uncle Israel and his family at Westwood

John Knowles 24 - Mining Engineer
Martha E. 23 - Housekeeper (sister)
