He advised silence, secrecy and Scotland, although they married in London; the marriage was opposed by her brother.
Prohibition of marriage between certain degrees of kindred outlawed what is known as incest; prohibition between degrees of relationship by marriage (affinity) as opposed to blood (consanguinity) seems to have reflected an analogous taboo.
