Colette, all births and deaths 1876-1877 happened in Deysbrook Lane, West Derby, no house number given.
Address where she died, on her death certificate was 10 Poplar Road, Upton, informant William R Lunt Son in attendance of 125 Boaler Street, Liverpool.
Her husband is buried in St Mary, Walton on the HIll, 16 July, 1877, address West Derby. Page in Burial Register 127.
I have an extracted list of all Lunt names at Walton Church from 1593 up to 1922 and she's not on it, another reason for assuming she is buried on the Wirral.
There is a possible burial for Mary (Page 164, death after 1877 and before 1883) but I don't have details - yet, need to confirm the age and exact date.
