family name COMBER in norfolk MISSING

[FRAN]

i have been looking for my great great grandmother who was born in norfolk and finally found her and i have now got a hard copy of her birth certificate

her name ROSINA COMBER - DOB 7 Feb 1873
born i think it says BARRACK street - definitely in POCKTHORPE NORWICH which was a sub district of EAST WYMER

her fathers name JOHN COMBER - occupation book maker

her mothers name EMMA COMBER formerly Mofs i think (not very legible)

I have looked on 1871 & 1881 census but no where to be found

ROSINA married Edward Longbottom in Halifax in 1890 and they appear on the 1891 census in Lancashire

i would like now to see if Rosina had any brothers or sisters and what happened to her mother & father

can anyone help me ??

thanks in advance
