Who is Adam?

Does anyone have any evidence as to who the parents of Adam HENDERSON are?

Adam was:

• born abt 1815 Southdean, Roxburghshire, 
• married Janet EASTON in Oxnam 2 days prior to the 1841 census, 
• lived Swinside, Oxnam (1841), 
• popped up in West Middle, Cavers in 1851, 
• Hallrule Lodge, Bedrule (1861) and 
• Newton, Bedrule (1871) 
• before emigrating in 1873 with Janet and son George, 
• settling in Alma, Jackson Co., Wisconsin where several family already were.

Why am I asking?
I'm investigating an excellent DNA match between a descendant of Adam (via son Peter), myself, and two of my cousins (2nd and 3C1R) where we all descend from Peter SINTON & Jane WIGHT.
The most likely line of the match's pedigree that accounts for this is that of Peter Oliver HENDERSON who turns out to be the son of Adam and Janet (EASTON) HENDERSON

The indications currently are that Adam is highly likely to belong to Peter SINTON's family somewhere.
But where?

There's an 1808 marriage of an Oliver HENDERSON (Hawick) to an Isabel SINTON (Cavers) in the Cavers Parish register, which looks promising.
Although there's no further info known, the couple fits the timeframe, place, and naming pattern to be Adam's parents.
If Adam and Janet's son Peter Oliver was named for both Adam and Janet's fathers we do have a bit of a problem as the above Peter SINTON's sister Isabel, who is of an age, is accounted for and I don't know about any other Peters.

So, I'm on the look out for others claiming descent from any of the above who may already have joined in the fun of dna testing for genealogy, or be prepared to, so we can compare results and
confirm that the dna match is indeed pointing to Adam.
Missing bits of the papertrails would also be most welcome - a Wisconsin death record/obit for Adam naming his parents? The fate of Oliver HENDERSON and Isabel SINTON?

Check out Adam on FamilySearch  FamilyTree for some of the descendants identified / linked to date.

TURNBULLs to FAMILTON?

Still digging away at verifying the link back from my McEWAN descendant Sarah Margery JOHNSTON who married a George Miles/Myles TURNBULL, back up George's TURNBULLs to, supposedly, John TURNBULL and Bessie FAMILTON, the latter being of Earlston.
Admit I'm having a bit of trouble with the chain of evidence.

Can spot John and Bessie (FAMILTON) TURNBULL having children in Melrose, with John saying he was a weaver of Gattonside at his 1718 marriage.
Can spot what looks like their son Thomas marrying Peggy FORSAN and having several children in Melrose, including a John in 1769.

The trail back from George Miles TURNBULL reaches a Thomas TURNBULL married to Helen TAIT, with Thomas stated as born Melrose on both 1851 and 1861 census records, about 1804/5.
I've not seen his 1891 NZ death cert (which implies a birth abt 1801), but at least one tree assigns him to a John and Jane/Jean (CURRIE) TURNBULL, who married/called banns at Cavers (John) and Eckford (Jane) and were having children baptised 1794 (Gattonside) through 1806, but with no Thomas recorded.
The Melrose OPRs also record the burial of a John TURNBULL, feuar of Gattonside, aged 73 in 1827 (so born abt 1754), who would seem unlikely to be the 1769 baptism of John son of Thomas and Peggy (FORSAN) TURNBULL, who didn't marry until 1766.

There is a 1753 baptism in Melrose of a John to John TURNBUL & Janet USHER of Gattonside, witnesses James & John BOSTON, which surname also features as witness to the 1794 baptism of John and Jane (CURRIE) TURNBULL's daughter Janet in 1794, and as cautioner for the 1743 marriage of John TURNBULL to Janet USHER (both of Melrose).

Anyone else interested in these TURNBULLs with any comments? Until more info is available, I'll disconnect the link in my WorldConnect database LornaHenderson.
