Dnallov,
It occurs to me that there IS a possible paper route to locate Peggy Richard’s’ biological mother.
1) You note that in Census 1921, Peggy’s birthplace is given as Isleworth (Middx).
2) What was the street address of Frank & Florence in the census?
3) From FreeBmd, the Hale/Richards marriage was at Uxbridge (Middx) in Q3, 1913.
4) Note both known locations in Middlesex; is street address also in Middlesex?
One hundred years ago, childbirth outside of marriage carried a lot of stigma, and many unmarried women would give up their baby for adoption.
5) If we assume that the birthdate of 20-Nov-14 is true and that the mother named her daughter Margaret, we can enter search parameters into FreeBmd to locate possible birth mothers. This is possible because an illegitimate child will be registered with the same surname as the mother.
A search of FreeBmd for,
sex: female
start date: Q1, 1913
end date : Q4, 1915
County: Middlesex
First name: Margaret
finds about 2230 matches.
Inspection to find the same surname for mother and child gives only a few hits.
Q1, 1913: Edginton; Mason
Q2, 1913: Dennis; Elworthy; Holland; Lightfoot*; Murphy; Storey
Q3, 1913: Haines; Hall(s); Julian; McCabe; Reade; Singleton*;
Q4, 1913: Hurcomb; Lockwood; Skates; Startin
Q1, 1914: Brock; Butcher*; Curtis*; Dowling; Hager; Welfare; Wolstenholme
Q2, 1914: Bullock; Dean; Erith; Glaysher; Meadowcroft; Sawyer; Smith
Q3, 1914: Black*; Davies*; Duncan; O'Connell; Soer; Vale
Q4, 1914: Black*; Chapman; Curley; Goldsworthy; Miller; Peacock; Penn; Savage; Smith; Winton
Q1, 1915: Brown; Connolly; Edwards; Godbeer; Lloyd; Lutt*; McCarthy; Millington; Parry; Wallis
Q2, 1915: Bedford; Coe; Harragan; Hawley; Herd; Lockstone; Mayers; Morrell; Scase; Walker
Q3, 1915: Banks; Brophy; Dodd; Fagan; Faithfull; Fitzgibbons; Knowles; Milting
Q4, 1915: Barnes; Botten; Dollery*; Rees; Spurgeon
where Name* = registered in Brentford, but cannot for the life of me remember why I thought that Brentford is important!!! Ah yes, close to Isleworth where they are living in 1921.
Peggy Richards' birthday is given as 20-Nov-14, which is Q4, 1914; illegitimate births for Q4, 1914 are given below,
Q4, 1914: Black*; Chapman; Curley; Goldsworthy; Miller; Peacock; Penn; Savage; Smith; Winton.
Now only 10 lines to check, so should keep you off the streets for a while.
Good Luck,
JMB
