Vivek sounds wise, but taken; Rohan is to ascend; Vinay is humble; Nathan means 'He gave'; John 'God is gracious'; Johan is a variation but means the same; Steve was a hit but too popular; Tarun is young; Nihar doesn't ring any bells; Timothy was a faithful companion, 'honoring God'; Luke, Joshua, Gabriel are all nice; How would Simon or James Cherian sound; I liked Caleb; She liked Joel, 'the Lord is willing'.
On the other hand, Grace is so good, should it be first or middle; Cloe is verdant; Venus; Stuthi is praise, hard to say; Suma, Linsy , Nanma are all mallu; Meghan is taken; Kripa is grace/blessing/mercy (depending on context); I liked Lydia; She liked Esha; Hanna, Emma , Eva, Divya, Ria, Tina, Vinney Jr are all nice. Mercy can be the middle , but will it go well with Grace or Faith.
You see..
