I am making a diagram of the property showing all the plants that flower and when. I have terrible luck in finding the plants doing a search and more often than not come back here to ask for identification. So again I find myself not able to identify this lily. Thanking you in advance for your assistance in this matter.

It is Hyacinthus..,,.commonly called Hyacinth.

I agree, that lovely plant is a The Hyacinths Database
Hyacinths (Hyacinthus)
Many listings in the database here: https://garden.org/plants/sear...

Thank you. What threw me was the leaves. My plant has thinner leaves where all the images I looked at had broader leaves.
