Silence in the 1800s

I was born to Fiona and Joseph Martin. I was one of seven children, five being girls, me and my brother, Sebastian, being the two boys. My brother lived to the age of nineteen, and was engaged to Stephanie O'Neill, the daughter of a lord in Great Britain. She was to bring the family wealth. Sebastian however grew ill with the common influenza, and passed before his marriage would take place. After his death, I kind of just stopped talking. My parents took their frustrations out on me and my sisters, and my sisters pretended he was never alive to begin with. I wouldn't talk until I was 18. And even then, only few words would be spoken. My tongue would twist and I would be yelled at because my speech was different. My family would hear those few words, and my mother would cry while my father would ignore me until a younger child would embarrass him, then he'd beat the words from my mouth.
