can anyone help me think of name variation?

My husband's mother's name was Ofelia. She died of cancer before we got married. He loved her so much and still misses her. She also treated me like a daughter and I wish she is here to see her grandson or granddaughter (we don't know the gender yet). 
We have been praying for a boy but I can't seem to come up with a boy name derived from Ofelia. I would greatly appreciate it if someone can help me think of boy names. Thanks!
