I have a number of entries to make to my family research software but I don't believe I have found much on John Taylor except his birthdate (1838). So your listing may be a possibility. However, without my having anything either prior to his birth or afterward, it is difficult to feel very sure, with a name like John Taylor. There were numerous Taylors apparently in PEI, which complicates matters.
I will keep your posting for future reference and hope I can come up with more details to help determine any connections. Thanks for writing!
