Let us pause in our narrative to discuss his name.
First off, the surname. Jones is too common and too boring. We also didn't want to saddle a kid with a hyphenated name. Some years ago we read about how kids with hyphenated names get married (especially to another person with a hyphenated name) and then they don't know what to do and surely don't want to have a string of hyphenated names such that they begin to sound like a late 19th century German prince. Cich is unique and interesting, plus there are a big bunch of Ciches, whereas at this point no Joneses that we are in relationship with because my sister's last name is Adams, my mother's last name is now Stanford, and my Dad was an only child.
Sebastian is simply a name that Michael and I have both liked for a long time. I think Michael was the first one to mention it in conversation, and I immediately agreed to it. I link it in memory to the crab in Little Mermaid, of course, but farther back to the boy in Neverending Story (a movie Michael and I both loved as kids). Of course there is also St. Sebastian. I'm often drawn to his images in art, and Michael and I saw many representations of him in our 2011 trip to Italy.
Interestingly, Sebastian was rare in America until the 1990's, so we Gen X-ers must like it. Since then it has been on the rise, peaking in 2012. Last year it was the 34th most popular boys name in the country, according to this website. According to this one it is "global hit" currently ranking in the top ten in countries as diverse as Chile, Denmark, and Austria. The same website says that it is a sophisticated name, which fits with current trends in US baby naming.
Some people have wondered about nicknames. We aren't going to automatically pick one, assuming that a nickname (if needed) will arise on its own. Some think Sebastian too long. Well, if so, then this website lists 16 different nicknames and shortening of the name which are already common. My preference has been for Basti. His mom's mom calls him Bash. And one of my friend's kids already calls him Bash Bash.
Briston is the middle name of one of my great-grandfathers, Arthur Briston Adams (which is a superb name). I've always liked it and always wanted to use it and am glad that Michael liked it as well. According to this website, there were only 3 Briston's born in the US last year.
He has a very diverse name--a globally popular first name that is originally Greek; a very English, old-fashioned middle name; and a surname that is an American shortening of a Polish-German name.
