I see you are keenly interested in Aianos. I've only recently started untangling them in my tree. I share your frustration with the misspellings which just about balance out the benefits of an unusual name with probably only the one original migrant.

My 1st cousin 3X removed Ada Eleanor Wardle (1879-1936) married William John Aiano in 1904, West Ham Essex. He was a greengrocer's carman in 1901 and died in 1906. When I recently took out a subscription to 1911 census I was stunned to find an Ada Aiano and 2 children living with a different Aiano, Arthur Ernest. He doesn't seem to be a brother of William John. Maybe some kind of cousin. I've been trying to untangle the tree and see how they are related. Here's what I've found: Does this link with any of yours?
Ada E Wardle's first husband, William John Aiano was the son of John Aiano and Eliza Green and the grandson of Edward Aiano and Mary Ann Style. I cannot see how Edward is related to the original Christmas Aiano.
Arthur Ernest Aiano was son of Charles Aiano and Frances Anley and grandson of Charles Christmas Aiano and Sarah Ann Giles (who is in your tree I assume). According to FreeBDM and Ancestry he married Ada Edith Indge in 1899. There's a death of an Ada E Aiano in 1936 in Essex, but is that Ada Edith Indge or Ada Eleanor Wardle? There are also Ada Aianos who died in 1963 and 1967. Now I'm confused. I've found no sign that Ada E Aiano (nee Wardle) remarried in England.
Just been over all this as I write and see that the 1911 entry is probably Ada Indge because she's been married 11 years. I can find no other sign of my Ada Wardle. Maybe she's emigrated?
What do you think?
