Hello everyone

I am a Holroyd by marriage and I'm making my husband's tree as a surprise present. I am reaching some dead ends, on the generation I could start looking up the census which is a shame! They are mostly in and from Halifax. I posted this also in the Holroyd board, I hope it's OK.

So any help appreciated. This is what I have so far (starting from present):

From his dad side (Halifax):
Paul John Holroyd (1977-)
Father: Philip (1952-2008)
Gfather: Wilfred (1918-1966), Gmother: Annie Hanson (????)
GGfather: Walter ?????, GGmother: Annie Wright ?????

From his mother side (Holcrofts from Halifax and Harvey's from Pontefract and or Bradford):
Mother: Sandra Holcroft (1953-)
Gfather: William Henry (1923-1988), Gmother: Dorothy Harvey (1929-2009)
GGfather+mother on Holcroft side: ??? Holcroft and ??? Edwards
GGfather+mother on Harvey side: Albert B Harvey ??? and Rose Foster

Any information on my question marks will be highly appreciated!
