&wf = "and wife," &ano = "and another" or "and one other" But you don't index those descriptors.

From the Field Help for Grantor and Grantee Names:

When typing the name of the grantee, do not include descriptive words or terms, such as "by Atty," "et al," or "and spouse," that may have been written with the name.
