At the 2x great-grandparent level, we have eight families in the tree. This page provides a brief sketch of each of these families. As will become clear, the Johnside side of the family (Johnson, Buckton, Lupton) was firmly northern English, mostly Yorkshire with a sprinkling of Cumbria (Bell). The Bryans side brings in the Celtic branches: the Bryans themselves originated in Ulster (county Tyrone). The Burn-Murdochs hailed from Gartincaber in Stirlingshire, the Mitchells from New Cumnock in Ayrshire and the Nisbets from Lanarkshire, near Bothwell.

Ancestor: Walter Johnson (1842-1915)
N.B. For a more detailed overview of the Johnson family, read this.
Johnson is a very common surname in the UK (probably top 10) (and I believe it may actually be the most common surname in America, or close to). It's evidently a patronymic, derived from John's son, which explains its popularity. From Patronymica Brittanica (hereinafter "PB"), we have:
The Johnsons, unlike many of the other families on this page, are hard to pin down. The roots of the family, insofar as we can trace them to the mid 1700s, are London. The family then transferred focus to the north of England (mostly Yorkshire), via one generation in Buckinghamshire. We see Johnsons living and working in Middlesborough and Tyne & Wear (briefly) before settling in North Yorkshire: East Rounton, Ingelby Arncliffe and Hutton Rudby. The Isle of Skye was briefly added to the family through the marriage of Hilda Lupton and Walter Lyulph Johnson and indeed, Burkes Landed Gentry (1972) refers to the family as the Johnsons of Strathaird. The next generation stayed in Yorkshire or moved further north again, to the Scottish Borders.
1b. The Bells
Ancestor: Margaret Florence Bell (1847-1930)
From PB:
Another possible origin is related to bells themselves: Bell could have been a surname given to a bell-ringer, or someone who lived near a notable bell.
Ancestor: Alan Lupton (1846-1918)
PB says, simply, "A township in Westmoreland [now part of Cumbria]". That would probably be this location. The origins of the toponym date back to the Domesday Book in 1086, listed as Lupetun meaning the "farmstead of a man called Hluppa".
Our Luptons were very firmly Leeds-based, hailing from a stock of cloth-merchant and clothiers. Darnton Lupton was the major of Leeds in 1844 (aged only 38).
1d. The Bucktons
Ancestor: Emma Buckton (1849-1938)
Another simple definition from PB: "A township in Yorkshire". Presumably this village near Bridlington near the East Yorkshire coast. Much like Lupton, the name Buckton probably originated as a combination of the words Bucca and tun (meaning farmstead); in other words, "the farmstead of Bucca".
The Bucktons, like the Luptons, seem to have been based in Leeds, latterly around Potternewton. The family, like the Luptons, was involved in the wool trade, though George Buckton switched out of this into more general engineering.
Ancestor: Arthur Bryans (1852-1944)
Bryans is most likely a patronymic, derived from "Bryan's [son]". There seems to be a lot of overlap with Bryant (in some old correspondence, Hal Murdoch Bryans is referred to as Bryant, and in details of his ancestor Francis' marriage to Grace Cross in Burkes', Francis is also referred to as a Bryant).
The Oxford Dictionary of Family Names4 has this to say on the surname:
The roots of the family start in northern Ireland, in County Tyrone, with Francis Bryans. His son Richard moved to Chester and many subsequent branches remained there, or close by in Shropshire. The Bryans were prolific in the number of children, so nowadays there are Bryans cousins spread all over the country, from Surrey to Cumbria.
2b. The Burn-Murdochs
Ancestor: Annie Jessie Burn-Murdoch (1856-1929)
The Burn-Murdoch surname originated very recently, at the union in 1820 of John Burn (1793-1862) and Anne Maule Murdoch.
Murdoch is a common Scottish name, both as a first name and as a surname. Two Gaelic words are said to possibly form the origins for the name: Muireach, meaning "seaman", and Murchadh, meaning "sea warrior".
Burn (and Burns, Burne, Burnes etc), are, according to PB:
Ancestor: Hugh McPherson Mitchell
Ancestor: Agnes Lockhart Nisbet (1866-1955)
Our Nisbets originated in Carphin, near Bothwell in Lanarkshire. A standard theory (e.g. that of Alexander Nisbet in his Heraldry of 1722) is that the Nisbets of Carphin sprung as a brunch from the Nisbets of Greenholm, but this link has never been proven. From Lanarkshire, there was a brief sojourn in Nevis in the Leeward Isles (e.g. Walter Nisbet (1707-1765)), including a tangential glance with Lord Horatio Nelson. Then stints in India, before returning back to Wimbledon.
