In Van Gogh's family in his art, how is the Vincent van Gogh of the Family elucidated?

Vincent van Gogh was born on 30 March 1853, exactly one year after the stillborn delivery of Anna and Theodorus' first child who was named Vincent.  As a child, he liked animals and flowers.  In temperament, he was strong, energetic and strong-willed.  Vincent enjoyed playing outdoors and made up games for his brothers and sisters, once rewarded with the most beautiful rose bush in the garden as his award.  There were a few times that Vincent exhibited his artistic talent and upon receiving praise from his parents, he destroyed the items.  He attended the local school but his interaction with the peasant boys was making him tough. As the family grew, a governess was brought in to tutor the children at the vicarage.In 1864, Vincent, aged eleven, was sent away for schooling to a nearby boarding school in Zevenbergen which led to his lifelong feelings of being an exile. In 1866, his parents decided to send him to the new and prestigious Willem II College in Tilburg. In March 1868 Van Gogh suddenly returned home. During his two years at the Willem II College the painter C.C. Huijsmans had been his art class teacher. As Van Gogh entered adulthood the divide widened.  After failing as an art dealer and in the ministry, he decided to become an artist.  The more his family members suggested possible alternative vocations the greater the gulf between Vincent and his family.  Further, Vincent's manner of dress, behavior and unusual love life was unsettling and embarrassing to the family.  By 1881 Vincent had developed his personal view of the world and religion which was very different from his parents', finding organized religion too constrictive. He wrote to his brother, Theo, "I find Father and Mother's sermons and ideas about God, people, morality and virtue a lot of stuff and nonsense."
