Hoping you are still at the same email address...I have a Barzillia Thomas Chinn married to Merilla Sired 1882, in Ontario, Canada. Barzillia was born Helston County of Cornwall in 1846. His parents were James and Argent Chinn. I've located him in Wendron in the 1851 & 1861 census in Wendron (actually listed as Ching but later listed as Chinn). He was a miner. Any idea if these Chinns are in your tree?
