This Daniel is proving very difficult !
I have the birth certificate of his daughter Rose Hannah Barnett born 1880
which states father Daniel Barnett mother Mary Jane Barnett(formerley Woolley.
I hadn't been able to trace a marriage of Daniel Barnett before but from this birth info. I found that Mary Jane Woolley married a Donald Barnet in 1864 Spalding which would be right. The only census I am sure Daniel is on is the 1871 with Mary Jane (both wrongly transcribed as Bennett) at Spalding
By the 1881 census only a few months after Rose's birth Mary Jane Barnett is shown living in Effingham St Sheffield and in marital status says living apart from husband, with her and her 3 children is a lodger William Greenwood.
She and William have a child together c 1883 and they eventually marry in 1898.
so I am hoping that the only suitable Daniel I can find is the one in 1851 at Legbourn, so am hoping legbourn is near to Granstone ? which he sates in 1871
Hope I haven't confused you even more
