You are absolutely going have some familial encouragement and support in any field. I was one of few of my math peer group in high school and college who didn't have Ph.D parents. (I had plenty of support, and but not direct parental direction in math. They drove me to the library and to my math team practice before school. I can't imagine how they could have given me nearly as much support in chem lab... And I even did a college chem lab one summer in high school, as part of a math summer program!)
