Annie E Tindall nee Ann Elizabeth Dowson married John Tindall in 1883 in bridlington, John and Annie only had 2 sons, harold W Tindall in 1885 who on the 1911 is living with his wife and daughter in rudstone and the census records he has been married 3 years with one child, and the other son was stanley morris tindall born 1896ish. There is a daughter Lilian b 1888 who in 1911 is aged 22 unmarried and living in Rudstone. I think she is a reasonable candidate for being Cyril's mother as her sister selina would have been too young to have a baby in 1907, I think lilian married a Robert Norris at scarborough in 1916 possibly and she died in 1945, but i can't see any other child of Annie E Tindall being the father/mother of cyril
