Allium Ursinum (I think)

I fell in love with these during Lockdown when I first noticed them. I recently put up a Blip of some that I had picked and put into a vase. I asked for help in identifying them. Today I explored a large patch growing on the Green near to me. I think they are Allium Ursinum. Thanks to the Blippers who helped me, especially my sister and Maurice1948.
