Yes, that was my mistake about the mixup between Frederick and Frederick Augustus Piears. Too many Piears I think.
This is my family line:
Frederick Piears, married Sarah Ann Moore Dec 14th 1845 at St Johns Waterloo.They had at least 10 children including Frederick Augustus and a daughter, Sarah Harriet. Sarah Harriet married Thomas Went on 4th October 1875 in Islington. Thomas and Sarah Harriet had a son, Thomas Walter Went, born 23rd June 1876 Islington. Thomas Walter Went married Catherine Ellen Clark on 4th June 1894 in Highgate. Thomas Walter and Catherine had a son, John Walter Went born 5th October 1896 in Islington.
John Walter Went married Annie Elizabeth McKenzie. They were my grandparents. Their daughter Joyce Marie is my mother. As far as I know most of the Went family from Islington emigrated to Huonville,Tasmania after the First World War with the exception of my grandfather who was badly injured as a soldier so his application to emigrate was rejected.
I'm afraid I don't have any stories about the Piears family to tell you. Perhaps anything of interest went to Tasmania with the family. I would be very interested to know how you found out where William Piears came from and about his Army career. All I have is Frederick's marriage certificate to Sarah Ann stating that William was an officer in the Army.
Perhaps you can help me with this - whilst checking the parish registers of St Luke's Chelsea looking for the baptism of Frederick I found a Frederick Piers/Piearse, parents William and Ann, of Pond Place, Chelsea in 1820. There is a similar entry for a Joseph Pierce, parents William and Ann also of Pond Place in 1815. William is listed as a labourer in both entries. There were also other entries for George Piers 1818, Eliza Ann Piers 1823 and Edward Piers 1825. Do any of these names mean anything to you?
