Zechariah BELLIS's parents were Edward BELLIS & Anne (nee HARRISON) ( Mold Parish Register)
According to the 1861 census when a Mary BELLIS was staying with her grandmother- her name was Elizabeth then a widow. Back in 1841 her husband was an Edward but not the above Edward.
So there must be another Mary BELLIS somewhere
Listed on the 1841 census for Zechariah & Eleanor's family there is an Edward, a pauper aged 75.
Zechariah was aged about 35- in 1851 he was 49. Is the Edward his father- possible I suppose
Thanks again for your help
