From Civil Service Evidence of Age Records :
" I , Parnell Gale , Head Constable of the Royal Irish Constabulary , 29 Patriot's Hill , City of Cork, declare that my son Parnell Gale was born at Peacock Lane in this City on the first day of June 1844 ..... and that he was 24 years of age last June ....there is no other record of his birth except that entered in the parochial register of the parish of St Ann's , Shandon , Cork... "
I think this is the correct Parnell Gale as he is on the 1901 Scotland census as a supervisor in the Inland Revenue ( Civil Service ).
