Hi Cynthia. Thanks for the answer and the interest. The information I have has Catherine Farrell as the Head of of the House (No record of her husband). She had 3 other children, the youngest being 6 years older then Denis Haydon (nurse child). It is entirely possible that, as you suggest, that this was a form of day cre.
I will keep digging and if I find anything else I'll post it.
