Notes

• After he inherited the Cowpen Hall estate, upon the death of his uncle in 1804, he continued to reside with his family in London, where they were distinguished for their benevolence to the poor and destitute.
  
  He was buried in old St. Pancras Churchyard. All trace of his grave has long since disappeared. This burial ground is a spot of considerable historical interest as the last resting place of many distinguished foreigners who fled from the horrors of the great French Revolution, when Mr. Sidney proved such a generous benefactor to the destitute nuns from Cambrai. In more recent times the churchyard was sadly desecrated by a Railway Company and what was left of it converted into a public garden.

James Horne alias Green, chaplain at the Venetian Embassy in London.  Mr Sidney became a very staunch catholic and took an active part in the affairs of the body.  After leaving Cambridge he resided at Clarendon Square, Somers Town, till he inherited from his uncle, Marlow Sidney, the Cowpen Hall estate, Northumberland, where he died July 12th 1839 age 87.  He was succeeded by his son Marlow John Francis Sidney Esq.
