What boy names "match" Hayden and Eli? I don't want rhyming names or even the same letter...but I just want a flow if you know what I mean. I don't want one kid named Rain and one kid named Walter. I'd like for them to mesh well.
Ok, here is my 2 cents. I love love love the name Tegan and it is not something you hear often. I also love the name Leland. Congrats on the babies too!
My lil Logan was mili seconds from becoming an Xavier, but my bestfirend ruined it by making the statement "living in California he's going to be called Javier all the time." Thats not cool. I have a Zachary as well! I also wrestled around with Quentin. Call him Qwinn for short.
Your names seem to be pretty common ones; both in the top 100. The Social Security's website for popular baby names can show you the top 100: 100 Most Popular Names for 2005. You might find something on there that you like. From that list I like Isaac, William, Robert (though its overwhelming popularity over the last 100 years has made it somewhat of a joke: witness the Almighty Bob in one of the Hitchiker's Guide to the Galaxy books), Hunter, Lucas, Brian, & Cole.
I just had my baby in March but I named him Ashton Gabriel. I have a Jacob and a Zachary so I still got something biblical but I definately wanted something different at the same time. I caught a lot of heat from family members thinking I was naming him after Ashton Cutcher, however, that was not the case at all. I do get some reactions when I am out but I am finding it is either a name you absolutley love or one that you really dont! Good luck!!
I always wish I had named my son Aiden (it's James Nicklaus--James for my DH and Nicklaus for his favorite golfer). But Aiden is too much like your Hayden. How about Wyatt?
