Female version of Adam?

Great suggestions from PPs.
what about:

Ada May
Ada Maeve
Ada Matilda

or

Eve Ada May
Evelyn Adeline
etc

Madeleine or Maddy as contains all the letters of Adam.

Seriously don’t lumber your daughter with a name you don’t like in order to honour your BIL. I’m sure he wouldn’t have wanted that.

Ada is a good option if you like it, Eve would also work. Either would be more than enough, IMO.

Maybe it doesn't have to be his name but something else associated with him? We lost 2 sons before having our daughter and wanted to honour them, but in a subtle way (their names didn't have nice female counter-parts either). As it turned out, the name we both liked best also happened to be a colour we associated with our late younger son. So we chose a middle name using the colour we associated with our late older son. I won't say the names we used but think names like Violet, Ruby, Lavender, Jade, Amber and Rose.

I would just say keep others other than dp out of discussions

This is the best idea. And frankly it doesn't matter about family preference

I mean it's a lovely idea but surely you can only do it if you have a boy. As a female, I''d bloody hate to be called Adam.

I actually really like Adamay. I think that’s really pretty, it doesn’t look that pretty written down but when you say it Ada-mae it’s nice!

In fairness whilst it’s nice to include his name, she has to live with it and having Adam as a middle name for a girl is a little out of the ordinary. I’d personally go with Ada. End of. She’s your baby not a name plaque.

Team Ada. Making up a name like Adamina just sounds rather silly. I understand the want to celebrate the whole name, but it’s just not always possible with the opposite sex. I wanted to use my late mums name as a middle name, but we had a boy and couldn’t find an appropriate way to do so, so we picked a non-related name.

Don’t let your in-laws put pressure on you, you (and DH of course) get to decide, though I know it’s a sensitive subject.

Is something like Araminta too far removed?!

Could you have 3 middle names so initials spell A.D.A.M?

Tbh i think just using Adam is nicer, or save it for a boy if appropriate.

It's her name, so you need to be happy with it.

Adam is a lovely name, but I think it's crazy that you are having to choose that name for your daughter. It must be terrible that he has died, but I can't see naming a girl with his name is going to help things

This is a great suggestion and so much better than those dreadful made-up names in the OP.

Adam is a lovely name. You're not honouring him by butchering it with random letters on the end to try and make a girl's name. If you absolutely must use it, just use Adam. There are girls called James and Dylan and Cameron and so on. Just have a girl called Adam/Adam as middle name if you absolutely must.

Amanda? I mean it does have all the letters?

People make up names, I once knew an Evanee so maybe you could go that route...? Not my cup of ☕️ but..

Adamie
Adamya
Pradamiya

There's got to be something better!

Hadamia!
Padama?

The family suggestions of made up names are all awful!

it’s a girl so if you use the full name it’d sound like two surnames eg Ada Adam Smith.

What about a double barrel first name like
Ada-Marie , I think that is beautiful

Could you clarify what you mean by 'family preference'? Who else gets a preference in your child's name other than you and her father?
I understand that your dh's family have lost a loved one way to soon. But I'm a bit concerned about the apparent need to have his full name represented in your daughters name.
You don't say how recently they were bereaved but it feels a bit uncomfortable to me.
Your suggestion of Ada as a reference but not full replication sounds more than appropriate.

Eden? It's not "adam" but it is a female name that sounds similar and has origins closely linked with Adam.

If it could possibly be accepted then look for other names with meanings associated with "Earth"

You also mention what the family want. I'd suggest not consulting with them further (DH aside), announcing the name when baby arrives and telling them how it links to BIL. Naming in memory of someone is a lovely thing to do but equally I know of a woman who has a male middle name in honour of a deceased uncle who she never met, and she just finds it mortifying. It has to be done in a way that's fair on you (i.e. you get a choice) and also fair on the child when they probably won't ever feel the level of connection to BIL that those of you who knew him have.

I'm team Ada. Perhaps with an 'm' middle name? Not Mae!!

I think depending on the first name you are choosing for your baby and what your surname is Adam is an ok name to just use as a girls middle name, but maybe give her a girls middle name too. The reason I think this is because Adams is also a surname. Said allowed to eg a doctors receptionist they would just assume the Adam/s middle name was a surname. I don’t think anyone would think it was unusual or strange. So, - first name-girls middle name- Adam/s- surname.
A middle name is hardly ever used, and even when she did use it I don’t see a problem with it.

I wouldn’t try to force a name out of Adam - Adamina and Adama really don’t sound right.

I think Adeline is a lovely name. You could always merge the first and middle names eg Adeline Amelia, but that is quite convoluted! 😂

Reverse it and have Mada? Usual spelling is Maida, if you like that - then it would still have Adam in it.

Female version of Adam would be Eve IMO - first man, first woman. But I'd either save the name for a son or go with something like Ada. I can't think of any way to feminise Adam that seems nice.

And yes Ada with middle name starting with m is a great idea!

I like @Whinge‘s suggestion too.

If you think it has to be Adam in its entirety in one name, you could think about:

Adamine
Adamaris (Ada-Maris for pronunciation)
Adamary (Ada-Mary for pronunciation)

Or did your BiL have a middle name that might be easier to honour?
