Sooooo....using the 1881 census listing that you located compare the names and ages of the kids and places of birth and there is little doubt this is the right family. Perhaps they didn't really adopt the Ross surname but the enumerator just sort of made it so.....but then again maybe they did! Only way to know for certain is to search for a marriage for one of the kids or some future event and see which name they stuck with.
Now back to the elusive Elizabeth. You know..... I'm not so sure that 1881 housekeeper entry you found is the right one. If it is....well....then it looks like that same lady is alive and well and living in Carnwath for the 1891 census. But according to Jane's DC you know that her mother was still alive so that
could fit. But the Elizabeth Bryce you can locate in Carnwath in 1891 is listed as Single?....also is listed as born Dunsyre like the housekeeper lady was. Also seems to be living next door to another Bryce widow first name of Margaret. I've checked and this Margaret dies within a few years and her parents are named on her DC. I checked the IGI for other births to these same parents and sure enough they did have an Elizabeth but she was born 1810 Dunsyre....which might fit your Elizabeth but then again might be a little on the old side. Very frustrating as Carnwath, Dunsyre, and Covington are all well within reasonable range to fit the circumstances. The thing is I can't find a DC for this Elizabeth either.....which only makes me think she might be yours. I mean what are the odds there are two Elizabeth Bryce's whose deaths cannot be located!!!!
Hope I haven't confused things further....
Best wishes,
Jean
