Ehm...but first, please forgive me for my poor English.

Central figure in our 'tribal myth' is Bundo Kanduang (meaning Biological Mother), The Greatest Queen all the time. Our clan (family name) descent from mother to children. Men and women with the same family name consider as close family, so prohibit to marrying each other (this has inspired a lot of fictions).
Women inherit tanah pusaka (clan's property).

My late grandmother from mother and my mother are the only daughter, and I only have brothers. Technically, according to our culture, my family lineage has ended.

I don't have problem with matriarchy. In fact, my grandmother got a medal for her works, so did my mother.
