Hello Monica, thanks for this, I have tried several times to find my paternal Grandmother Euphemia Meldrum Glen and her family on 1901 census without success.
I entered Henry Glen today, result for 48 Baker St only gave me Henry and then Margaret Stewart, a grand daughter - who's?. But I have the Birth cert copies for Euphemia and Henry giving birth place as 48 Baker Street, Stirling. What the Drummond connection is I do not know as I can't get a full read of who as living at 48 Baker street 1901, totally puzzled just to find Henry and Margaret.
I have family moving to Camelon, nr Falkirk after 1901, as last child of 7, Isabella, was born there 1904 and Gt Grandfather John died 1911 in Camelon. Also found, which you state, Henry sailing to USA 1930, occupation stating as a moulder.
Have to keep digging, this is now bugging me
Bill
