dates fit and would tie in with Wm Harrison + Roeder also W W Gill who was the generation post Harrison and may have confused ann boyd with the more famous ann wade (or the tale he recounted must have been 50 or 60 years in the past).

I can't locate the marriage between John Boyde + ann Wade jnr - the baptismal entry for Robert in German implies illegitimacy but the Kk Michael for Ann implies married.

ann wade als cannel is buried kk michael 23 Mar 1844 age 76 and probably d/o patrick cannell + ann caley if IGI is to be trusted (I havn't yet checked the KK Michael bapts of this period)
