For a one-syllable name it sounds long and dwan out when I say it. the s a the beginning and end makes it seem hissy and the oam makes me want to emphasize the oh sound by saying it s bit longer so for me it sounds like SOOOOOOOOOHMZZZZZZZZ or something like that. Bram is alright. I don't understand why fns have to match, so I really don't understand trying to make mns cohesive. Soames and Bram are fine together.
