Hi Kimberleyx,
Welcome to Rootschat!
Background for us to reference - what you have:
US to CANADA:
George B JAMIESON, age 17 (b abt 1910)
28 Feb 1927. Travelling alone
Farm Labourer, b Glasgow Scotland
Aunt Helen McMILLAN, 309 Church St, Windsor Ontario
CANADA to US:
George B JAMIESON, age 16 yrs & 11 months (b abt 1911)
3 Sep 1927. Accompanied by brother, William JAMIESON
Farm Labourer, b Glasgow Scotland
Relative/friend from whence Came: Aunt Helen McMILLAN, Sandwich, Ontario
CANADA Ocean Arrivals:
22 August 1924 Sailing from Gourock, on SS Montlaurier
George JAMIESON age 13, Scholar, b Scotland
Going to Canada, permanently, to join his father, William JAMIESON
At address: 309 Erie Street, Windsor, Ontario
Relative whence came: Grandparents, Mr & Mrs Edward Nixon, Saltcoats.
Form signed: by mother, Mary JAMIESON
Not entirely sure he was really going to join his father? It says father - but I'm noting: His older brother William JAMIESON, appears to have arrived in Canada in 1923 to settle and work.
So from all that - we hoped to find either George's father with a sister Helen/Ellen JAMIESON or George's mother with a sister Helen/Ellen NIXON....and:
NIXON, is your connecting line
A tree on A*y
Edward Moore Nixon and Grace Baxter, Scotland, Glasgow, Saltcoats connections…
Had a daughter Mary, b 1885 (no details on spouse, issue, death etc)
Had a daughter Ellen, b 1897, died Richmond, Macomb, Michigan in 1990, aged 93, but no spouse name
I find:
Detroit Border Crossing: Canada to Detroit Michigan, USA
12 Oct 1927
Ellen McMILLAN
Accompanied by Husband John & children
Age 30 years, 11 mths, b Glasgow
Last Place of residence: Sandwich, Ontario
Going to Join: Sister, Mrs Jamieson, 1225? Vermont, Detroit, Michigan
Been before in US for Occasional Daily visits to Detroit
Relative whence came: Father, Edw. Nixon, Saltcoats, Scotland
So, George's mother's sister Ellen is it. Ellen/Helen often interchanged on records.
Cheers
