He was the son of James Blackler (2.9.1804) and Eleanor Harris Blackler. (born Blackler - she was the daughter of Daniel Blackler and Elizabeth Harris of Ipplepen)
Samuel had two surviving siblings, Edward(1833) and Susan Eleanor (1835).
James (1804) was the brother of my G.G.G. Grandfather, Edward Blackler (1808). James parents were Thomas Blackler - Elizabeth Rowe.
I can let you have more details if you are interested.I must take no credit for this - it is all my Aunt’s hard work !Apparently you contacted her (Joyce W.) a couple of years ago but she had no information on Samuel at the time.
