I am looking for information on Mary Catherine "Kate" Moore's parents & family.

Born Nov. 27, 1849 in Virginia.
Died Feb 15, 1929 and buried in Roanoke, VA.

Father = unknown Moore
Mother = Lucy Slaughter

"Kate" married Abraham H. Goodpasture, they first lived in Smyth County, VA, Wythe County, Tazewell County and then in their elderly years, in Roanoke, VA.

I have been unable to locate her in the census sheets.

She may be listed as Mary Moore, Mary Catherine Moore, Kate Moore, Mary C. Moore....?
Does anyone have her in their family tree?
