How do you come to William Richard CLARK?
I think two Williams have been confused.
I don't have the 1867 marriage details -
I presume you do as you need those to confirm this James is 'your' James, son of Robert & Ann (Philip) CLARK But working from what I can glean - I have found
James CLARK married Elizabeth SIMPSON St George, Edinburgh 1867
Elizabeth Jane CLARK mother SIMPSON born 1868, St George, Edinburgh 1871 census 60 Tintern Street, Kirkdale, Liverpool, Lancs
James CLARK 27, Steamship Engineer born Scotland

Birth registrations are on GRO and digital images can be bought to confirm
William, from those censuses, married Ellen Christina Bridge in 1905. Image is on Ancestry. William is 26, an Engineer and father is James Clark, deceased (no occupation given)
But marriage of
Elizabeth Jane Clark, in 1887, is on a tree on Ancestry. She names her father as James Clark, Engineer.
And so William Richard CLARK and James Christopher CLARK are different people.
