Hi
I'm also interested in this family and may have some other information to help, I am descended from Daniel b 1856
Regarding the occupation of Robert Wright 1825, moving from weaver to stoker to fireman, this could be from the time when the local weavers moved to work in the big mills in Auchterarder, and some of them were responsible for the boilers for the steam to power the looms.
Lilias Maule's parents may have been William and Janet Anderson
I have found numerous variations of the name McKeich mostly McKeith so I now search on both.
cheers
re the two Robert's in 1861 the other Robert was living with his aunt Helen Donaldson, his parents were William and Jean Donaldson
the information on our Roberts death certificate lists his father as William and mother as Mary Ritchie (also found recorded as Richard).
