Many thanks for replies - have only just seen them. I don't know why I said Sarah and Walter were married in Lancaster, the newspaper entry says St Mary's church, Liverpool and the marriage registration says West Derby - so sorry about that.
Florence Ellen Seconde's birth was registered D Qtr 1882 Worcester. I think the death entry for Wigan is likely correct. Edwin's Will was for £127 left to his son John Samuel, so didn't think there would be much to help in his Will, but can obtain it. John Samuel Cook, out of all his children, was the least of them to need £127 !
