Hello Dash,
Your family on the 1881. census still at 177 Garngad Hill, Glasgow.
Wm. Barclay, Head, General Lab. M. age 46 years, M. born Alva, Banff,
Christina Barclay, Wife, M. age 46 years, F. born Forres, Elgin,
James Barclay, Son, Porter, U. age 18 years, born Forres, Elgin,
Elizabeth Barclay, Daur, Scholar, age 13 years, F. born Dalis, Elgin,
Jane Barclay, Daur, Scholar, age 9 years, F. born Glasgow,
Annie Barclay, Daur, age 6 years, F. born, Glasgow.
I do not have the actual 1871. census. for the family. but by doing a search on Scotlandspeople, i am sure they are still in Glasgow, ie High Church, Glasgow.
Young Alexander Barclay, is with them, so as he is not there with family on 1881. i did another search for Alexander Barclay, deaths and there is one in High Church, Glasgow, 1871. aged 6 years, so i reckon Alexander, died sometime soon after the 1871 census was taken.
The clues are there that it is Alexander, because his young sister Jane Barclay, was born 12/Feb/1872. High Church, Glasgow.
Regards,
Jonn.
