Here is a link to the Pray More Novenas website, which also lists other Novenas that you can do and can sign up for, if you are interested:
They will send Novenas to you if you want them to to your e-mail inbox as a reminder to pray them if you want to sign up, but you’re not obligated to do that. I am signed up with them. It’s a nice service to get the Novenas as a reminder to pray them with others, I think.
You can just look at the website at the Novenas that you would like.
They have a listing of more common Novenas, and they also have Novenas to our Guardian Angel, and to St. Michael the Archangel, too.
God bless you and your family, and I hope that your Uncle is doing alright.
