Possibly the mother of Joseph Anthony McHugh found here:
"England and Wales Census, 1901," database, FamilySearch(https://familysearch.org/ark:/61903/1:1:XSX7-CGW : 8 April 2016), Joseph Mchugh in household of Elizabeth Mchugh, Saltney (Flint), Cheshire, England; from "1901 England, Scotland and Wales census," database and images, findmypast(http://www.findmypast.com : n.d.); citing Hawarden subdistrict, PRO RG 13, The National Archives, Kew, Surrey.
This shows a Joseph McHugh, born 1885 in Saltney, living in Saltney, working at the age of 16 as a Labourer. His mother, Elizabeth McHugh is listed as Head of the Household - age 56 born approximately 1845. She was born in Gateshead, Durham. No father is listed. There are 3 siblings, all born in Saltney - Philip (age 18), Edward (age 13), and Elizabeth (age 11).
There appears to be some validity to this, as the 1911 Census shows him with Caroline and his children and extended family:
"England and Wales Census, 1911," database, FamilySearch(https://familysearch.org/ark:/61903/1:1:XW3X-QDZ : 2 August 2017), Joseph Mchugh, Chester, Saltney, Cheshire, England; from "1911 England and Wales census," database and images, findmypast (http://www.findmypast.com : n.d.); citing PRO RG 14, The National Archives of the UK, Kew, Surrey.
