Hi Carol,
Ilderton is very close to the Border and looking in Roxburgh I found the baptism of Helenor daughter of George Turnbull & Mary Laidlaw baptised 31 August 1834. This is in the Yetholm register.
Looking back to Wooler registers which cover Ilderton, in the Cheviot Street register there is the baptism of Mary Laidler on the 25 January 1811, daughter of Thomas & Eleanor Laidler of Flinthill, Ilderton Parish. she was born 29 December 1810.
Also in Cheviot Street baptised on the 10th April 1837 is Mary Ann, daughter of George & Mary Turnbull of Millfield Plain, Kirknewton Parish, born 3 April 1837.
I hope this is your familly!
