My dad is on the ancestry websites constantly, digging up interesting tidbits like this and connecting our family to Blakes and McCallums, but no Smiths or Johnsons.  Geneology is interesting, and it makes us wonder how some names get popular and others don't so much.  It's a lot of work reproducing at such a feverish pace, so nice work Browns, nice work.

This also makes us wonder why some Johnsons are related and some are not.  Things that decrease the probability of having a common ancestor:

• If the surname refers to any occupation (such as Smith, Cooper, Baker, etc.).

• If the surname is a color, thing or place (such as Black or Underhill).

• If the surname refers to a physical characteristic (such as Small).

• If the surname refers to the son of someone (such as Anderson or Johnson).

Fascinating!  Whatever your family history, congrats to all of you Smiths and Johnsons, on being Treasure Valley royalty.  Let's have some huckleberries and a craft beer to celebrate.
