Hi Kim
Son William born 1859, looks to have married Elizabeth McKinnon in 1882 in Old Kilpatrick, Dunbarton (ref 501 / 53).
I think this is them in 1891:
William Clark 32 Rivetter b. Glasgow
Elizabeth Clark 32 b. Glasgow
Ellen Clark 7 b. Old Kilpatrick, Yoker
Robert Clark 7 b. Old Kilpatrick
Alexander Clark 3 b. Glasgow
William Clark 5 months b. Glasgow
Address 9 Lyon Street , Glasgow/Milton
By 1911, the family look to be in Ireland. Address showing as 118 East Bread Street (Pottinger (part of), Down. See
www.census.nationalarchives.ie/reels/nai002198812/From the family's entry in 1911 and going by the birth places and ages for the younger children, the Clarks look to have been in Ireland pre 1901.
