Hi Speedy
George Pilbeam, father to Harriet was my 4 x gr grandfather. According to the 1851 census George was living at Battenhurst Farm, Ticehurst, employing 120 people.
According to my records for the Pilbeam family, and apologies if you already have any of this information:
Harriet and Thomas were married at Dallington in 1842. thomas died at West Malling in Kent. Thomas & Harriet were lodgers of George Card and his family on the 1881 census, the address was Church Fields, West Malling, Kent. Thomas was a 63 year old labourer and Harriet was aged 60. That confirms that.
Children of Harriet Pilbeam and Thomas Simmons are:
i. Annie Simmons, born Bef. 16 August 1843 in Battle or Catsfield, Sussex, England; died 09 August 1914 in Pitlochry, Perth, Scotland.
ii. Thomas Simmons, born Bef. 22 September 1844 in Catsfield, Sussex, England; died Aft. 1891.
iii. Eliza Simmons, born Abt. 1847 in Battle, Sussex, England.
iv. Harriet Simmons, born Bef. 13 October 1850 in Ticehurst, Sussex, England.

vii. Joseph Simmons, born Bef. 29 July 1855 in Ticehurst, Sussex, England.

Also this is a theory of mine but one of George's sons, James (my gr x 3 grandather) married a Sarah Simmons born 1815 in Penhurst. I think she may be Thomas's sister. Her father was called Thomas and I am still looking for him. If I find anything more I will let you know.
best wishes
