According to 1871-1891 English census records, Ella or Ellen Elizabeth NIGHTSCALES was born at Halifax, Nova Scotia. Her father, Henry Nightscales, born 1842 at Sleaford, Lincolnshire, England, was not in the index to the 1861 English census, nor can his marriage to Elizabeth be found in the English indexes.
I would be interested to confirm the date of Henry Nightscales' marriage to Elizabeth, and also her maiden name. I suspect it might be Smith, as their first son born in 1877 in Lancashire, England, was named Henry Smith NIGHTSCALES.
