Help with solution?

I run a christian based aa meeting on friday nigths at church.They also have whats called amininity.We go by first names only.We also have a clothing bank open to aa people on friday nights.A miliyary person wants the last names of these people but I cannot break their aninimity.How can I continue to provide clothes to the aa group and satisfy the new clothing bank women who runs it and wants their last name?She is military and all about rules ,Please help.

Just tell tell the other guys the situation and tell them if they wish to give her their last names, they may do so. It's their last names after all, not yours, so it's their decision.
