I am really confused about William Peter Glascock's children and who was his wife. The 1870 census looks like the following:

1870 census Mt Carmell PO, MT Carmell, Fleming Co, KY, 18 June, P-462
Peter Glapcoch head 45 m KY Carpenter
Rachel Glapcoch wife 26 m KY K H
Daniel Glapcoch son 1 s KY

But the 1880 census has a different wife for Peter plus the incorrect age, state of birth and possibly occupation. Or is this 1880 census not William Peter Glasscock? I've been given different names and ages for his children than this census shows.

1880 census Elizaville, Fleming Co, KY, ED-32, 4 June, S-8d, P-548
Pete Glasscock head 48 m IN IN IN Farmer
C. Sopha Glasscock wife 35 m IN IN IN
Dan Glasscock son 16 s KY KY KY Farm Hand
Pete Glasscock son 14 KY KY KY attend sch
Billy Glasscock son 13 KY KY KY attend school
Sam Glasscock son 10 KY KY KY attend school
James Glasscock son 9 KY KY KY attend school

Fannie Glasscock dau 6 KY KY KY attend school
