Man, my head is spinning, but I think I have some resolution on Mary Munro Murdoch. Thank you Deb for typing this out:
"Isabella Murdoch, residing at Pentridge, near Melbourne, Australia, only child of the late Mary Munro or Murdoch, (daughter of the said Catherine Munro)..."
The problem lies in that this gives us bad information (is an error), that simply doesn't work with the math. Ann b. ca 1806-07; her dau. Catherine b. ca 1833-34 could NOT have had a daughter Mary born ca 1831-32. My first error was trusting that the Gazette words written by a Edinburgh barrister were gospel... they can't be. Mary Munro Murdoch could only have been the daughter of Ann Chisholm.
And she was. For some reason she was staying with her uncle and grandmother in 1841, rather than with her family, and that added grist to my bastardy theory. Altho' I can't find any of Rod Munro and Ann Chisholm's 3 daus in scotlandspeople, under Munro, I DO find Mary, christened 17 Feb 1832, on Family Search under MONRO, dau of Roderick Monro and Ann Chisholm. That should put that to rest...

I spent 2 hours at FHC without much success; did find Elizabeth Chisholm Bayne with family in 1861. I had about 6 families to check in immigration records, and neither vol 1 of Whyte, nor the 2 volume Smith, Leonard H., Nova Scotia immigrants to 1867. (Baltimore, MD : Genealogical Publishing Co., 1992),
was useful. For example, tons of Alex Chisholms, but fact they were married and/or all traveling with children, or not right time frame made me eliminate them
Both White and Smith put emphasis on pre-1800 and very early 1800s migration.
I'll review all the posts while I was away again, and see if I need to respond more.
