You will have to try and follow me with this, ok in 1871 there is a entry for john o'day age 26 ireland, margaret kane ireland wife age 48 bernard kane 1864 stepson and mary1866 step daughter both bernard and mary born runcorn,
i found bernard birth 1864 both in free bmd and cheshire by putting in mother margaret and i have bernard cain volume 8 page184 and mary ann 1866 volume8 183 if you notice both are back under cain and not kane, so if right margaret was born ireland and her first hubby passed away, i also found a mariage for 1867 for a john o'day and margaret cain in warrington in cheshire, i can send a postal order for bernard cain birth if someone puts me in right dirrection as can only send postal order,,
