Hi again,
This is a tricky one. It would be pretty hard to prove that George and Millicent Stanley are actually George and Millicent Castelnovo, unless you can find a clear link between the Stanleys and the Castelnovos or Longs.
I took a quick look for the Stanley family in the 1901 England census. I only found two George and Emilys, but neither have a daughter names Dora, although one is Dorothy but the birth date is all wrong:
George Stanley born 1858 Wooton Bamt Wilts
Emily born 1861 Wales
With sons John and William, daughter Ellen Richard and son-in-law Robert Richard, living in Stratton St. Margaret, Wilts.
George Stephenson Stanley b. 1864 Huddersfield Yorks
Emily Stanley born 1863 Bradford Yorks
Daughter Dorothy Edra Stanley born 1893 Leeds, living in Holbeck.
Let us know madridmama if there are any other look-ups that might help you solve this! (or if you want full refs for above)
I also tried poking around the Lanark County, Ontario Genweb site, but there doesn't seem to be any mention of this Stanley family. Here's the link:
