Any pregnancies prior to my own birth must have ended either in miscarriage, stillbirth or baby died within a very short time (minutes/hours) of birth. I have checked FindMyPast and the only recorded birth - using maiden name and surname - is my own.
Also checked Parish records on FindMyPast but I don't think they have North Yorkshire yet.
My father did not serve in the armed forces during W.W.1. I have his Army Reserve, Certificate of Protection, issued Munitions Area, Recruiting Office, Middlesbrough. Dated 11 May 1917. I rather think - as in W.W.2. - those who could not go on active duty served in a home protection capacity. I do remember in W.W.2. my father going out, on what I think was, Air Raid Warden duties. Could perhaps have been Home Guard, really not sure it was a long time ago. I doubt there would be Army Reserve service records.
Many thanks for all suggestions and information.
