Thank you very much for the replies. Lots of info and the other Rootschat post to research

. It will take a little time so may be a while posting back on the facts of this.
Yes I have other Armstrong's in my Family Tree too who are elusive, they seem to have an affinity to Little's.
Don't know if this helps but the Walter I am after is indexed on SP as
GRAHAM WALTER
Father JOHN GRAHAM OR ARMSTRONG Mother MARGARET TELFER FR415 (FR415) M 30/06/1816 814/20 264 Canonbie
Just a bit of info on my family. Monica, some years ago you helped me with Charters Jackson & her illegitimate daughter b 1855 Agnes Jackson/Armstrong. Agnes's father was a Robert Armstrong b1826 Priorhill Canonbie. I am now trying to prove that Walter could be the half brother of Robert. Their father being John Armstrong c1791
Through DNA I now know that Robert A* b1826 is definitely the father of Agnes. May be repeating myself now

So would like some ancestors of John Graham/Armstrong to show up.
My DNA & some of my Armstrong relatives is on a well known Ancestry site and would like to know if there are any of Walters decedents DNA on any DNA site so we can compare.
Thank you again for all the help.
Will get back shortly.
