Welcome to Just Answer and thanks for your question. Can you clear up some geography for me? Where is Glascow? I'm not that familiar with Australian geography and the only city with a similar name that I am familiar with is Glasgow Scotland.
Do you know where Patrick and Rose Ann were born and approximately when - even within a decade helps?
Sorry: Glascow Scotland is correct.
Patrick stated he was born in Kilwinning, Scotland Parish Ayrshire (on the coast, west of Glascow). His DoB is problematic as, on a 1940 army form, he gave Dob as 14 May 1889, but on a 29 Dec 1914 form he said his age was 26 years and five months which would make his DoB about 29 July 1888. (Maybe he was bad at maths?). He named his Father as Thomas McAlear, a railway plate layer.
Patrick's Army records show Rose Ann Sammon was a waitress in Glascow, aged 31 years on 24 Jan 1917, her father James Sammon, Plasterers labourer. Their wedding on 24 Jan 1917 was at St Lukes Catholic Church, Wedding Reg. No. 35. in Hutchesontown District.
Thanks for the clarification. The issue arises because of the spelling. The city in Scotland is Glasgow, not Glascow. It is a charming city and the natives pronounce it GLAZ-go with a short a.
