The first recorded spelling of the family name is possibly that of Adam Medecalf. This was dated 1301, in the Subsidy Rolls of Yorkshire, during the reign of King Edward 1st, 1272 - 1307. Surnames became necessary when governments introduced personal taxation.In England this was known as Poll Tax.t is chiefly recorded in the county of Yorkshire, and there have been claims that it represents the very first hereditary surname. This is arguable, but there is no doubt that it was one of the very first.
As for tooth decay, conventional dentistry says that sugar alcohols do not promote it and the United States Food and Drug Administration (FDA) agrees. In fact, you will see claims - sanctioned by the FDA - that one sugar alcohol in particular, xylitol, PROTECTS teeth from cavities. Even though this is odd that on one hand, dentists say sugar causes tooth decay, but then on the other hand they claim that sugar alcohols can protect against tooth decay.
Sterilize is the wrong term. The alcohol kills a lot of the bacteria and slows new bacteria from growing. But it doesn't kill all bacteria and it doesn't stop it from growing completely. If it is strong enough to sterilize, then it would be like drinking bleach, it would probably kill the human.
