Unbiased opinions please!!

Trinna
I really need your unbiased opinion!! So here goes... My sister in law has 3 kids I am about to have my third. Devontae, Dai-Juan, Darryn(her 3) Demitrius, and Denali(my 2). My brother-in-law had an affair. Not just an affair, but he had a baby from his mistress. My brother-in-law is Richie and the baby's name is Rishawn. I am madly in love with the name Roman for my little man. I know I can name the baby whatever I want. I know that my sister-in-law will not be nasty no matter what I name him. My question is: Do you think she will be hurt inside?? Is it like a slap in her face to name him an R name??
