Re Elizabeth Brown, bc 1855 Paisley Renfrewshire, daughter of David Brown and Elizabeth Cook - probable marriage to John Letterick 1874 Glasgow.
That certainly looks like her - I think this is the family in 1881, although the transcription of the children's names is hopeless:
1881
Dobbies Loan, Glasgow St Rollox
John Letterick, 30, carter, Mockrum, Wigton
Elizabeth Letterick, 26, Barrhead, Renfrewshire
Daniel Letterick, 3, Glasgow (this must be David - there is no Daniel registered)
Thomas Letterick, 1, Glasgow (this must be James - again, no Thomas registered)
David Brown, 20, boarder, Edinburgh
And looks like that's Elizabeth's brother, David, lodging with them. He went on to marry Jean/Jane Rae in Glasgow St Rollox in 1890.
I've found 9 children of John Litterick and Elizabeth Brown - all born in St Rollox:
Hugh Litterick b. 1876 d. 1877
David Brown Litterick b. 1877 d. 1937
James McArthur Litterick b. 1880 d. 1950
Elizabeth Ann Litterick b. 1882 d. 1883
John Litterick b. 1884 d. 1935
Agnes Philip McArthur Litterick b. 1887 d. 1950
Matthew Brown Litterick b. 1888 d. 1910
Robert Brown Litterick b. 1890 d. 1959
Samuel Litterick b. 1892 d. 1895
Elizabeth Litterick (nee Brown) died in 1926.
I'm curious about the McArthur middle name for two of the children, as McArthur is my family name - although my McArthurs were still in Aberdeenshire at this time - they didn't make it to Glasgow until around 1920.
