The 1851 census shows William & Elizabeth still living in Calstock Town. Daughter Thomazine was visiting her grandmother Jennie (Jane) Sellick along with her cousin Mary Ann daughter of John Bailey Sellick.  Their daughter Hannah aged 12 was working as a house servant in Calstock.

By 1861 the family had increased to include Elizabeth (7) and Serena (3). The older children, Thomasine, Mary Ann, Joe and William were all working in the local mine at Calstock. Their father William was working on the docks as a quay labourer. 

Hannah Sillick had married in 1858  a widower, Basil James Woodd and was living in Hasland, Derbyshire in 1861.

Mining was widespread in Cornwall and there were many mines throughout the county. In the  19th century mining reached its peak, before foreign competition depressed the price of copper and later tin, to a level that made Cornish ore unprofitable. The Cornish Pastie was used originally by the miners as their food underground.  It was easy to carry, and could have savoury in one end and sweet in the other.

The family moved to the coalmining town of Cramlington in Northumberland in 1865. They were part of a group of miners from Cornwall called in to replace miners in Cramlington who had gone on strike in protest at their working conditions. (for further details see http://freepages.genealogy.rootsweb.com/~allpoms/neengland1.htm).

John Henry Sillick although recorded as the son of William was in fact the son of his daughter Thomasine.
Thomasine married James Warrick on 11 April 1868 in Tynemouth and was also living in Cramlington when the 1871 census was held.

By 1881 William is now a widower, his wife Elizabeth having died in 1872 at the age of 55. William, Elizabeth and Joseph have all left home.
John Henry is recorded as his grandson and there is a new addition to the family in granddaughter Elizabeth.  Elizabeth was the daughter of Sibbella.

Joe Sillick had emigrated to New Zealand, arriving in Auckland aboard the Baron Aberdare in March 1875. His name is recorded in the 1881 Electoral Rolls
for the Bay of Islands. 

In New Zealand Joe worked as a miner in Kawakawa where coalmining was the chief industry of the town.  

After his marriage to Jane Little on 11 November 1885 at the Wesleyan Parsonage in Pitt Street, Auckland, they returned to Kawakawa where they raised three children - William Henry born in 1886, Sarah Jane born in 1887 and Joseph James born in 1895.

Joe died on 7 September 1921 at 23 Buchanan Street, Glenmore, in Auckland.  He suffered with spastic paraplegia for five years before his death, an ailment characterised by progressive weakness and spasticity of the legs. His daughter Sarah who was married with a young family was living in Kingsland, and it may have fallen to her to look after her ailing widowed father.

Joe's father William emigrated to Clay County, Indiana, United States of America in 1877. He went with his daughter Sibbella and her family where they joined Thomasine and James Warrick who had emigrated to the States sometime between 1871 and 1873.

William Sillick died in Brazil City, Clay County, Indiana on 14 February 1895.
