Ancestry edit
"He is three-quarters French and one-quarter Italian in ethnicity."
I am changing "ethnicity" to "ancestry" here, because "ethnicity" is not being used properly. Ethnically speaking, Costello is American, or perhaps more specifically Louisiana Creole. French/Italian is his ancestry.
And just out of curiosity- the last name Costello is Irish, so how did that come into the picture?Jonathan f1 (talk) 20:23, 21 July 2020 (UTC)
