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.
