No, I thought they looked kinda like daylilies also, but I have been fooled by pictures before. I sent the link so you could compare what you have to the species of Carex that is native to your area and agree or rule it out. I figured if it was Carex, then that site would be a reliable ID source.
You mentioned you dug them up....did you look at the roots? Daylilies have tuberous roots as pictured in this link
