Hello second cousin twice removed, greetings from the homeland.
Archie also had a sister called Margaret 1811,
He & Margaret (Nee Campbell) had eleven children that I know of, a few I have found died either in childbirth or shortly after.
The 1841 census has them living at Whiting Bay with Christina 1834-1890, Martha 1836-1869 & John 1838-1909, I have traced these three until their deaths and what i think is all of their family.
Archie & Margaret moved the family to Greenock circa 1850 where they lived at 2 Vennel from 1851-1857, they then moved to 22 Sugarhouse lane until Archies death in 1876. margaret moved to Nicolson Street where she died in 1884.
1851 census they were living at Campbells Land 18 Heavey Lane ? (Harvey lane)greenock west, with Martha 15, John 10, Archie 7, & William 5
Your line; Archie McBride 1869-1937 married Sarah Nelis who had previously had a child with a James Kennedy called William, she then married Henry Edwin McGill they went on to have three children William, David & Margaret,
Archie & Sarah produced six children; Flora, Archie, Francis, John, Alexander & Edward
