Talk:Adams family political line

Talk:Adams family political line, Why would "Son-in-law of another John Adams" count at all as a descendent of John Adams. Sons in law are not counted usually in genealogical work????? This Will Smith is not in anyway related to John Adams. Right ? except socially, is genealogy  about this? Ocralle (talk) 18:22, 3 June 2008 (UTC)
