I agree. I thought it was weird when my mom kissed my uncle (her brother) on the lip in greeting but it is normal for them. Movie kissing made kissing apear to be a lot more intamate then they were.
Kissing on the lips was a common form of greeting in England in the 16th century. It would only have been a dry kiss, not a French kiss. They would not have thought it any stranger than kissing on the cheek. it certainly was not an indication of anythign incestuous.
