In the 1901 census she was with her family and born in West Bromwich abd in 1911 she was also with her family.  Her parents were reported to have been married for 33 yeears and to have had 16 children of whom 11 were then alive.  This made her parents married 1878.  Indeed there was a marriage then of a Thomas Morris and Emma Groom, confirming the maiden surname on the above birth record. (Phew!)

So her parents were Thomas Morris and Emma née Groom.

Using this information on the new-ish GRO database at <https://www.gro.gov.uk/gro/content/certificates/indexes_search.asp#Results>; produces the following children to a MORRIS father and a GROOM mother in the whole of England:

This is 16 such children born in West Bromwich.  The 1911 census records that Gertrude had had had 16 children, of whom 11 were then living.  The last one listed  above is Harry born in 1905 and by pure coincidence this is the same in the 1911 census aged 6.  QED?

The Muggleston births with a mother’s maiden name of Morris are:

Last name   First name(s)  Year Of Birth  Year Of Death  Year  Location
Muggleston  Rowland A      1921           —              1921  Leicester, Leicestershire
Muggleston  Dorothea G     1924           —              1924  West Bromwich, Staffordshire
Muggleston  June M         1927           —              1927  Birmingham North, Warwickshire
Muggleston  Ronald W       1929           —              1929  Birmingham North, Warwickshire
Muggleston  Geoffrey A     1931           —              1931  Birmingham North, Warwickshire
Muggleston  Norma          1933           —              1933  Birmingham, Warwickshire

In the Ancestry Tree, the first is blanked out and the last is completely missing.  But on the tree the blanked out one, in fact Norma, married a John W Bird who lived from 1928 to 2015 so this might be findable: they married in 1953; but his death was in Australia so the rest of the information will be a little hidden.  So move on to the next child, Dorothea, as Rowland does not seem to have married.

Dorothea m. David J Hocking in 1953 and they had 2 children, girls, Carol A born in Newton Abbot in 1956 and Nicola E born in Launceston, Cornwall in 1964.  Carol m. a Christopher J Palmer in 1979 and the electoral rolls of 2002 on show they had with them Cindy, David and Trevor, but the birth recoprds do not show any Palmer Children.  Nicola E R Hocking m. a Bradley L Smith in 1990 aand there were a load of Smith-Hocking infants.

Moving on to the next Muggleston infant, June M who m. Ernest Arthur Hollinrake (should be easy to find).  They m. in Q2 of 1957 in Birmingham and had 2 girls, Anne S in 1958 at Nuneaton and Gillian in 1960 in Sutton Coldfield.  Anne looks like she m. Anrthony Rothin in 1983 in Lichfield and had no children.  Gillian m. Leslie C Sprason in Jan 1984 in Lichfield and no children found for them either.
