The maiden surname of Alexander Montgomery's wife Mary has been given as McCullough and Mary Nevin. Are there any actual records to determine? Apart from a joint land venture, I have seen no evidence that she was a Nevin, No such connection was shown in Genealogy of Evans, Nivin, and allied families by Septimus E Nivin. The book appears to have been fairly responsibly researched. A first book by (Senator) Septimus E Nivin was published in 1922. He spent five more years corresponding and collecting, and died without finishing the updated volume. Alfred R Justice organized the material, but authorship of the second edition, revised and enlarged, printed in 1930, was still attributed to Septimus E Nivin.
