I’d love your honest opinion on this - our son will be here soon and [name_m]Lincoln[/name_m] is my top choice. The only problem is my name and DH both begin with “L”, and he is concerned we are going to be one of those super cute families that all start with the same letter. It does remind me of 19 kids and counting… but I love the name. What do you think about it?
[name_m]Lincoln[/name_m] is ok in a family of L’s as long as …
- the names are not too similar in sound or look ([name_f]Liz[/name_f], [name_m]Linus[/name_m] and [name_m]Lincoln[/name_m] would not be ideal)
- you don’t plan on having any more children
- you plan on having more children and have many more “L” names you love and would use (any future child may not want to be the only one in the family with a non-L name. It just wouldn’t seem fair).
unless you plan to follow the TV family by creating dozens of children with the same initial.
I think the best plan is to use the name you both love most. I don’t think that just because this child starts with L, all future children must too. My oldest daughter starts with a G and although we said the second child couldn’t be a G, if she had been a boy, he would have been [name_m]Griffin[/name_m]. There was just no other name that we both loved as much. And why should baby [name_m]Griffin[/name_m] not get what we thought was the best name just because his older sister happens to start with a G too? Why should baby [name_m]Lincoln[/name_m] not get your favorite name because yours happens to start with L too? Obviously this can be carried to an extreme (as with [name_m]George[/name_m] Foreman who named all his kids [name_m]George[/name_m]) but it’s my best advice.
I’d put it in the middle spot.
I think the most important thing is that you love the name you’ve chosen for your baby. If [name_m]Lincoln[/name_m] is that for you - go for it. I must add though, if you were to have another child, you would have to think carefully as to whether you would continue with this pattern (you may look like one of those families!) Or not (the second child may feel left out as the only one without an ‘L’ name). Good luck 
I think you should use the names you love and not worry about it! I also wouldn’t worry too much about being limited to using L’s for future children. I doubt a child with a different initial would think you loved them less or that they weren’t a part of your private club with big brother. Especially since they think of you as mom and dad more than by your first names.
Thank you all so much for your replies! It really is nice to hear other’s perspectives (especially since we’ve decided to keep the gender a secret from family and friends).
We would be: [name_u]Lisa[/name_u], [name_m]Luke[/name_m] and [name_m]Lincoln[/name_m], which sounds ok unless we end up calling him [name_m]Link[/name_m]. Calling for [name_m]Luke[/name_m] & [name_m]Link[/name_m] to come to dinner could be a mouthful 
I don’t think I’d throw out a name I absolutely loved for that reason, but it would annoy me a bit too.
But you do have to remember that after the first dozen years of his life that sort of thing won’t really matter to him. It’ll mean more to you and your friends/family than it will ever mean to him.
Though, are you planning to have more kids? Can you see yourself searching for names for #2 and being concerned about them feeling left out if they [name_m]DON[/name_m]'T have an L?
I really wouldn’t worry about it. I started thinking and I came up with a couple of families that I know that have parents and one child starting with the same name and I’ve never thought twice about it. My friends [name_f]Jessica[/name_f] and [name_u]Jamie[/name_u] have a son named [name_m]Jackson[/name_m] and a daughter named [name_u]Bailey[/name_u]. [name_m]Mark[/name_m] & [name_f]Maggie[/name_f] have a little girl named [name_u]Mackenzie[/name_u] and another named [name_f]Ava[/name_f]. It didn’t even cross my mind to think that [name_f]Ava[/name_f] or [name_u]Bailey[/name_u] was left out because her name didn’t start with M, so I think this might be a bit of a case of overthinking it a little. You might get a comment or two, but I certainly don’t think it would be enough to keep you from using a name you love.
