I posted a previous question about my great-grandmother before but I ordered her birth certificate from the New GRO index https://www.gro.gov.uk/gro/content/certificates/indexes_search.asp
However, the name of her father is missing. What are some reasons why he would be missing from here? How can I trace my family tree without this information?
Winifred Lydia O'Brien
BIRTH 30 OCT 1896 • Stroud, Gloucestershire, England
DEATH 28 NOV 1979 • New Westminster, British Columbia, Canada
I believe I have found my great-grandmother in the 1926 census of the prairie provinces. https://www.bac-lac.gc.ca/eng/census/1926/Pages/item.aspx?itemid=890822 Line 6 in the image.
She was also found in the death index: Winifred Lydia Fowler, "British Columbia Death Registrations, 1872-1986; 1992-1993" https://www.familysearch.org/ark:/61903/1:1:FL1S-HQZ
As well as in the 1901 England census: https://www.ancestry.ca/sharing/16091326?h=e6067d&o_xid=61785&o_lid=61785&o_sch=Email+Programs https://www.ancestry.ca/sharing/16091335?h=4da97d&o_xid=61785&o_lid=61785&o_sch=Email+Programs
