You say Vera Bigelow and I say Vera Biaglow

My sister gave me this daylily. She calls it 'Vera Bigelow', but I've been unable to find any mention on the internet of such a cultivar. There is, however, a 'Vera Biaglow'. She still maintains it's Bigelow and I know enough not to argue with an older sister, especially not one who shares her daylilies and hostas with me.
