hi ts
i,ve had a look in FindMyPast service/pension records for alfred but no luck on that front so i looked to find the census record you speak of and found this entry for an alfred green born chippenham in st georges barracks , trafalgar sq , by going back page by page it appears that the regiment is the coldstream guards as the first entry is for an hon orville nugent lieut in the coldstream guards so i,m presuming they all are coldstream guardsmen but don,t hold me to it , [ scrimnet what would be your thinking on this please ].
now in the 1881 cen is that your alfred and his wife susan living in lancs ?.
regards
trevor
