Hi
They've got me foxed in 1881

I've found what looks like John & Emma in 1891 in Manchester with daughters Minnie, Edith & Bertha.
There is a birth reg for Bertha Poston
s in Chorlton reg district for 1879 so they ought to be in Manchester in 1881 but they are evading me presently.
Found a death reg for Emma Poston
s 1896 Chorlton district aged 53.
I'm packing up for the night now but I'll have another go tomorrow unless you get sorted.
Regards
SandraC
