At some point, you seem to have omitted the words 'Foot Guards' from your notes. Were you aware of this? All the officers whose names you have listed were associated with the Coldstream Regiment of Foot Guards (2nd in seniority but only rarely referred to as the '2nd Foot Guards' or '2nd Regiment' - at least not within the Regiment, whose motto was 'Nulli Secundus'
, owing to their having been raised before the 1st Foot Guards back in the C17th.)
Your posting indicates, I imagine unintentionally, that your interest lies, rather, in the 2nd (Queens Royal) Regiment- which, despite its name, was not a Guards regiment
Might that explain some of your confusion?
