The simplest way of naming twins is thru the anagram method. In this technique, you can choose one name for one of the twins and rearrange the letters to form another name and give it to the other one. Some good examples are:
Daniela - Adelina
Aisha - Shaia
Alanis - Salina
Bert - Bret
The anagram method for choosing baby names suit parents that want a more unique type of name for their babies. These names coming from rearranged letters usually don't have meanings with them unlike traditional names.

Another option that you can use for finding a name for twins is thru the synonym method. A synonym is a word or phrase (baby name in our case) with the meaning that is the same as or very similar to, another word or phrase. A few good examples are:
Joy - Bliss
Avril - April
Aimee - Lovely
The baby names above has the same meaning with their partner, wherein Joy and Bliss means happiness, Avril and April obviously means born in the month of April and Aimee and Lovely means beautiful or adorable.

Reversing names from its last letter going to the first letter is another method, though it's a bit hard and you'll surely come up with a few selections. Choosing this method will require you some time for sure. Some of the samples we have found are:
Ami - Ima
Leon - Noel
Ellen - Nelle

There's a lot more method you can use to find that unique baby name you want for your twins. All you need is to be creative and have a vision of what you want for your new born when they grew up. You can try using same letters at the beginning of their names, or even find names that rhyme with each other. But whatever baby name you give them, always remember that the most important thing of all is your love and care for them.

Good luck and hope you'll find the baby name that you want.
