Provide admins the ability to choose to show last names first in the communication details column. Then, you could sort the information in the "Name" column based on that information.

For tracking Communication Details following Email communications from the website, the default list containing the member name and email address is sorted by "First Name", then "Last Name". The base sort for this view of the data associated with sent emails should be "Last Name", then "Property Address", then "First Name" such that members of the same household are grouped together in the list. (Note: The Property Address does not need to be displayed, and is only used for sorting)
This table is used as a quick hit to determine if specific "households" are 1. Not getting Messages, or 2. At least one member of the household has opened the blast email (or other communication).
