Thank you Monica - I spent a few hours doing the same.
I tried looking for them individually - just entering first names (with and without approx years/places of birth), then adding key words like 'Lapicide' and 'Fort' and not a single sausage.
Do you remember my query a wee while back regarding John Ann Chissel nee Gibson? Well, the mystery of her disappearance has still not been solved, but as she vanishes, a Kate Alma Douglas, actress, appears in London who matches exactly. No concrete proof that she's one and the same, but both have the same year/place of birth, same father's
first name, same connections to another 2 families in Stirling ........

But that's another story!! The Chissels I can't find in 1861 are her grandparents.
