Thanks so much for the help Shane. I am not going to rule this record you sent out just yet. Here is why: I do have my John Sheridan's death cert but: it did not list a Mother's name which I found out since the Informant was John's son - PETER. Seems strange that Peter would not know his own Grandmother's name. It also makes me wonder whether the Father listed as PETER on John's death certificate could have been a mistake - I can't rule that out.
Here is my challenge in searching the Irish records. All I know is that my John Sheridan came from Ireland. I don't know when or from what County.
John's marraige cert did not list any parents - it also spelled his name Shirdean.
I like your suggestion of checking for other Sheridans near where John and Elizabeth lived in Scotland.
Do you by chance have the correct links for the applicable census returns and Poor Law records?
