Hi Robert thanks for that, I'm also from Archie's son John Campbells line.
From there we split, I follow down through John's son Archibald (1869), His Daughter Flora Muir Swan (nee BcBride) (1904) then my grandmother Sarah McBride McMahon (nee Swan) (1927) known as Morag and then my mum Flora McMahon (1951) , oh and me 1970.
Talk about name repetition down the line too many Archies, John's and Flora's

They also all seem to be from Greenock after John Campbell until my mothers generation who moved to Corby in England and I now live in Australia.
Here's what I have on Archie:
Archie McBride (b1803- d1876):
Born in Kilbride, Bute on the Isle of arran in April 1803 (18th suspected) - Baptised 24/4/1803 - [O.P.R. Births 553/00 0010 0110]*
Parents of John McBride & Christina Robinson
Suspected Brother of Janet (1799), William (1801), Anna (1805), Alexander (1807) and Christian Sophi (1809) - as advised on this chain.
Married Margret Campbell (from Edinburgh)
Died at home (22 Sugar House Lane, Greenock, Renfrew, Scotland of Liver disease on 11/9/1876 aged 74 /[Statutory Deaths 564/03 0685]*
He had three children that i'm aware of: Martha (b.~1840), John Campbell (b.~1842) and Archibald (b.~1845)
It would appear that he was in fact described as a Deep sea Pilot - what ever that is

And I have Census records for Archie & Margaret's Household in:
1881 (Marg only) - [Census 1881 564/03 002/00 002]*,
1871 (Archie & Marg) - [Census 1871 564/03 029/00 001]*
1861 (Archie, Marg, Martha,John,Archie Jnr & Christina McVean grand-daughter) - [Census 1861 564/03 025/00 001]*
1851 - Cant find any census info that i can confirm to be them as yet
1841 - Nothing yet but belived to be in Kilbride.
*Ref taken from Scotlands People documents.
I've got some things on John also but i'll email them to you.
I've only been looking for a week so dont have masses of info but i'm happy to share what i've got. Can you pm me and i'll respond.
All the best
Gary
