Hi Cindy.
William Russell married Mary Jane Gracey, on the 2 November 1866, in Seagoe Church of Ireland, Seagoe, Lurgan.
Seagoe is between Lurgan and Portadown.
If these are the parents of Halliday, then the Russell / Halliday marriage I posted has to be wrong, as there is only 15 years between the marriages.
Both marriages are from Emerald Ancestors website, a very helpful resource.
