Hey Denise,
I found a Louise Williams with a Ernest Williams in 1880 in Nashville.
Tennessee > Davidson > Nashville Ward 13 > District 97>>
Walker, Mary 27 born TN parents born TN
Williams, Louise age 27 born Tn parents born TN
Williams, Ernest age 1 born Tn parents born Tn
The Mary Walker appears to be the head of household. What is strange is that there a line drawn through the Williams. I am not sure what that means. Hope this helps.
Tony
