I have examined more closely a copy of the 1865 Valuation records which MAY assist.
Please tell me what you think. About the attached record I can say this: they seem to jump around. That is between 3 Braeheads and number 4 we find an address in Duke Street, then 4 Braeheads then Fishcross Street then Broad Street, Braeheads again and so on. The organisation seems not to follow a path as much as it correlates to ownership. So John Bobbins Noble has his properties listed then the widow's Noble, then William Noble "Bildie", Mariner, Then William Noble, a draper of Broad St, and so on.
So far as I can tell the neighbouring houses on the 1861 Census with Widow's in them (Barbara Noble 46 in 1861 and next door Elizabeth Noble 51 in 1861) both Braeheads could match with the 1865 No's 2 & 3 Braeheads. Making them, respectively Barbara, widow of John Noble, and Elizabeth, widow of Peter Noble.
I have checked John "Bobbins" Noble's sons, and he did have a son John, who predeceased him, but in 1862 (at sea, off the coast of Africa, from all that I can tell.) So neither this John, or Peter, were his sons. Neither were the widows his daughters, which doesn't preclude their being related, of course, but doesn't enable me to narrow them down yet.
Enjoy the handwriting.
