I would argue its quite appropriate if you also use group checks for other things. How often in real life do people go,Seems like recalling lore is typically something that is not appropriate for a group check in the first place.
"oh its on the tip of my tongue, the guy's name was tim, tom..."
"Yes! Jim, yeah he was the web developer I worked with...etc"
Most lore checks involve something more than just a name. They often involve a name in a place with a date etc. Different people in the group might have slightly different pieces of that puzzle that adds up to the answer, or at least knows enough to suggest possibilities that trigger someone's memory.
