How to get my fiance to take my last name?

How can i convince my fiance to take my last name? He has an extremely common last name while mine is uncommon both in name and even more so in spelling. There are so many people out there with his exact name and if i switch there will be so many people with my exact name too. Im scared of identity theft if i switch names. Another reason is because there are no guys in my generation with my last name in the family, so the unusual spelled uncommon last name will die with our generation.
Any advise?

The mother has to consent to either of those things.

But by putting your name on the birth certificate, you are making yourself financially responsible to the child and its mother.

There is no chance at all that she'll want to give the child your last name, especially if she intends to raise it without you.

Just because your name isn't on the birth certificate does not mean that you can't be part of the child's life, or that you aren't the child's father.
It just means that, in the eyes of the law, another man is responsible for that child instead of you.

I wouldn't worry about things like the name or birth certificate right now.
I'd talk to the mother and find out why you were only JUST notified, if she wants you to be involved and to what extent, if she expects you to contribute financially, etc.
THOSE are the things that really matter. A birth certificate's acknowledgement of your genetic link does NOT make you a dad.

Legal question not a genealogy one

Depends on how quickly the solicitor processes the paperwork, the court stamp the fee/application and the newspaper prints the declaration

I'm an actress- I'm just trying to figure out a stage name for myself. I'm thinking of having Zalani as my last name and Saffron as my first. I love my roots, but I'm just tired of casting people inquiring about my ethnic origins and family history. I want the focus to be on me, not what part of the world I originate from. Does "Zalani" sound ambiguous enough as a last name? Any comments would be appreciated. My original last name start with a J.

Thanks!

Genealogy is about researching dead ancestors records from 70-100 years ago and back, unfortunately the sites like ancestry.com mislead people by saying things like " put in your name and your family tree will appear" that is simply not true, they do not have anywhere near enough records to do that and in many countries their public records which are records about the public up to 70-100 years old are legally not open to view, so unless your grandmothers are 100 years old you will unlikely find them on genealogy websites, if for example they were born in the 1950s/1960s you won't find them.

Start by deciding which country, then what date and if they are likely to be alive then try FB, as they are women and if they follow naming patterns then both/either could have married and so their names will be different anyway

I have to assume that you have his date of death and name, and hope he is on her birth cert. If he is on the birth certificate, she has the legal right of ordering a copy of his death record. From that, you will have the names of his parents, and can proceed to research through them.
Research, by the way.. is always based on a document or record of some kind. You certainly cannot "ask" someone about their parents in the 1800s. So, you just proceed with finding those records. As a general rule, records are restricted about LIVE persons.. but that does not mean you can never find information.
And you will need to be sure of the location. Just being "Mexican" is not specific enough.. he may have died in Texas, etc. Once you find a person coming from Mexico, you shift to learning what records are open for research, there.
