FAMILTONs and LEDGERWOODs

Further to the FAMILTON activity of yesterday, a bit more digging on the Northumberland families unearthed a John FAMILTON marrying a Margaret SENGERWOOD, or so the FamilySearch's England Marriages, 1538–1973 told me.
FindMyPast however has her as LEDGERWOOD, under which name she is indeed shown in assorted census records.
As my FAMILTON connection is on the branch of my tree including RICHARDSON/RUNCIMAN/LEDGERWOOD, I did a bit more digging to see if there might be a connection.
Jury still out, but I did quickly get back to Scotland from Northumberland as her father John LEDGERWOOD was born 1816 in Yetholm, to John LEDGERWOOD and Jean/Jane RIDDEL; John Snr being the son of William LEDGERWOOD or LIDGERTWOOD and Janet STEVENSON. I was interested to note that the 1816 John had a sister Helen/Ellen who married a James RICHARDSON, parents as yet unknown, but born Birgham around 1825, and emigrated to Melbourne, Australia on the "Marian Moore" in 1853.
My LEDGERWOODs hail from Jedburgh, with James, brother of my Walter, being tenant at Lanton in 1714, around which time Walter was at Hundalee.
Walter's last two known children were baptised at Eckford.

Relationships clarified & yet more connections

Reading old newspapers, as one does, I stumbled upon a different obituary for the Rev John FAIRBAIRN of Greenlaw than that I had previously seen. This one was in The Free Church of Scotland Monthly (Edinburgh, Scotland), 1 Jun 1895, and contained a new interesting little snippet for my FAIRBAIRN research: "Along with his more distinguished brother Dr Patrick FAIRBAIRN, Principal of the Free Church College Glasgow, he spent his youth at Hallyburton, ... while his two cousins Dr James FAIRBAIRN of Newhaven, and Dr John PURVES of Jedburgh, had their homes at farms a few miles further west in the same district."
I've been tripping over the Newhaven James often enough in the past but had never managed to place him in any of my known FAIRBAIRN trees, his death cert showing his parents as James FAIRBAIRN and Elizabeth TAYLOR, with the only other known (to me) family being an unmarried sister Eliza.
Knowing that the Rev John's grandparents were a James and Elizabeth (PURVES) FAIRBAIRN, and quickly finding out that Dr John PURVES was the son of Peter PURVES and Margaret FAIRBAIRN, with Margaret looking highly likely to be a dtr of James and Elizabeth (PURVES) FAIRBAIRN, I've now placed the Newhaven James as brother of Margaret and the Rev John's father John (marr. to Jessie JOHNSTON).
The informant for the Newhaven James' 1874 death was his cousin, a Peter someone of Ferry Rd.
I had initially taken a stab at the squiggle being THOMSON, but have subsequently confirmed that it is actually Peter Chas PURVES, who was living in Ferry Rd in 1881, Peter Charles being the son of the Jedburgh Dr John PURVES above, and being yet another minister in the family - presumably ministering to my own FAIRBAIRNs at Morebattle, given he was the Free Church minister there in the 1861 and 1871 censuses.
