Margaret Creer and Patrick Killip 1785

Hi, I am still having difficulty with this marriage at Lonan. I am trying to find children for this marriage. From Family search I have 2 certain. Joseph 1803 and Thomas 1808 because their mother was given as Margaret Creer.
The earlier baptisms do not give a mother. I am trying to find a son called John. I have found 2, John 1786 father Patrick and John b 1792 father Patrick. Please can anyone help me . Thanks
