[Adamanta]

I am a westerner and have been practising Sanatana Dharma for about a year. The local temples have been very accepting of allowing me to participate in everything and I was even elected to the executive board of a Hindu charity. But, there are a couple of things I am curious about, but a little hesitant to ask the local priests. Do I have a gothram or a caste? What is it? I'd like to participate more fully, by going through the various samskaras, such as upanayanam, marriage, namakarana for my (future) children. Can I do this? How should I ask the priest about these things?
