I am also researching the McGiverns that have an Edinburgh link. I am still trying to place this jigsaw together, but I'll share what I have, starting with my point of interest;
Michael McGivern, born 1845'ish Rock Corry, Co Monaghan, Ireland. First wife: Bridget Gange, died giving birth to Patrick McGivern 30 Dec 1866. Second wife: Helen McKenna, born 1845'ish in Monage, Dartry, Co Monaghan. Together they have atleast seven more children, as follows;
1.James McGivern b.1867'ish. 2.Catherine McGivern b.1869'ish. 3.John McGivern b.1871'ish. 4.Bernard McGivern b.1872'ish. 5.Anne McGivern b.1874'ish.(Married William Cline 1896). 6.Peter McGivern b.1875'ish.(Died 1900 in South Africa). 7.Michael McGivern b.1877'ish.(Died in New York).
(All this information has been passed along the family, so it may not be that accurate.)
So, the whole family up sticks and moves to Edinburgh, Michael being employed as a 'Scavenger'.
Patrick McGivern, born 30 Dec 1866 in either Ballybay or Dawsongrove, County Monaghan, Ireland, (child of wife number one), is my ancestor. He marries Catherine Keenan (or Kathleen, depending on which certificate you read) on 12 Aug 1890 at St Patricks, Cowgate, Edinburgh. At this time he is employed as a Mason's labourer, residing at No.18 Pleasance, Edinburgh, and has three children;
Catherine McGivern b.24 July 1892 Mary McGivern b.11 Jan'1894 James McGivern b.25 Oct 1902.
Catherine and Mary are born at 66 St Mary's Street, Edinburgh and James is born at 197 South Wellington Street, Glasgow.
So it appears that at least some of the family re locate to Glasgow between 1894 and 1902.
James McGivern b.25 Oct 1902, my grandfather weds Mary Gow b.7 Sept 1900 and they have three children;
Marie McGivern b.19 Sept 1934 (my mother) James McGivern Beatrice McGivern.
I have had a look at the 1881 census (for the family I am interested in) and have come up with the following; Resident at 4 Millers Close (171 Canongate), Edinburgh.
Bernard McGivern 5 years Ellen McGivern 40 years James McGivern 9 years John McGivern 11 years Mary Ann McGivern 3 years Michael McGivern 7 years Michael McGivern 44 years Patrick McGivern 18 years Peter McGivern 35 years
As for the 1891 census, I cast the net that bit further and came up with the following McGiverns in Edinburgh;
Bernard 16, Canongate District Catherine 25, Canongate District Charlotte 27, Newington District Helen 45, Canongate District James 60, Canongate District James 28, St Giles District James 21, St George District John 29, Newington District John 20, Canongate District Mary A 15, Canongate District Michael 55, Canongate District Michael 19, Canongate District Patrick 25, Canongate District Patrick 20, Canongate District Peter 10, Canongate District Sarah 0, Newington District
