Can't find Myra Brace nee Tromans in 1871. known as Tromans in 1871

1881 Myra born 1848 is living with her husband John Brace born 1836 and their son John H Brace born 1880 at Spring Hill, Hasbury, Stourbridge, Worcestershire, England. I have found the family in 1891,1901 and 1911.
I can't find Myra in the 1871 census. Myra married John Brace on the 21 May 1877 at Sedgley Parish Stafford.
In 1861 Myra born 1853 is living with her father Thomas Tromans and her stepmother Elizabeth  in Phillack, Cornwall. Thomas dies in 1863 in Cornwall
By 1871 Myra's stepmother has remarried and she is living with  Charles W Southorn and her children at Maughan Street, Kingswinford, Stourbridge, Worcestershire, England.
By this time the childrens' spelling has changed to Thomas from Tromans but no Myra.
Myra's year of birth changes througout each census but her place of birth which was Cradley stays throughout.
Added:
Myra was a Tromans in 1871,so added fact in subject line.

I have been looking for a friend and we have been pulling our hait out looking for Myra.

I will  have to the ask my friend if she knows the name of grandfather. That is one avenue we didn't think of.
Added:
I have asked my friend and she told me the grandfather is called William.
She has to look at  her information regarding his birth etc.
