Hi,
These are my thoughts:
FreeBMD has a Thomas A. Kirby born 4th Qtr 1914 in Orsett - mother's name MOORE.
1st Qtr 1894, Alfred Kirby m. Elizabeth Esther Moore in Orsett.
In 1901 Census, Alfred is 36 yrs (Horseman) and Elizabeth 26 yrs in Orsett. They have 2 daughters: Susan Esther and Annie. Also, Alfred's mother Susan, a widow 78 yrs.
In 1911 Census, Alfred now 46 is a Blacksmith Striker in a Cement Works in Orsett. Elizabeth, 38, has had 4 children - all still alive. The last 2 are Millicent (8) and Alfred (6).
Regards,
Kevin
