Hello! I came across a reference to this forum as I've been researching my claim to British citizenship via ARD section 4L. I believe my claim is straightforward (although I would certainly appreciate having others verify that I'm correct). However, there are some complications with the necessary documentation and I'd love to hear any ideas from the fine folks here about how best to approach them.

The claim:
My grandmother was born in England in 1934. She married my grandfather, a US serviceman, in 1954. The marriage occurred in England.
My mother was born in the US in 1957.
I was born in the US in 1984.
Were it not for historical legislative unfairness/gender discrimination, my mother would have been a British citizen due to her mother's citizenship, and upon my birth she would have been able to register me as a citizen.

The complication:
My great-grandmother was not married when my grandmother was born. My grandmother was given her mother's surname at birth. (For the discussion here, let's say that she was given the name Mary Jones at birth.)

My assumption is that at some point my great-grandmother married and my grandmother's name was changed to (e.g.) Mary Edwards, presumably to give everyone in the family the same surname. This is the name that my grandmother used as her maiden name, and it is the name that appears in the GRO register of marriages for my grandparents' marriage.

From digging around on the National Archives site, I've discovered that if the Mary Jones to Mary Edwards change occurred between 1939 and 1945, there should be a record of it, although thus far I have not found anything. It seems that if the change occurred before 1939, there was no requirement to register it, and given the circumstances, I would not be surprised if it was a situation where they simply started calling her Mary Edwards and that was the end of it.

Given all of this, my question is what documentation I should provide to support my claim.

I plan to request my grandmother's birth certificate and my grandparents' marriage certificate from the GRO. I will provide birth certificates for myself and my mother.

I found my grandmother's US petition for naturalization form, dated 1959, and I plan to request a copy of it as well. This confirms that she was still a British citizen 2+ years after my mother was born. The form uses her married name, but includes the date and location of her birth and the date/location of her marriage, both of which match the other information I'm providing.

Does that seem sufficient? Should I try to find a record of my great-grandmother's marriage? I know the surnames and likely (general) location, but not the year, so it will require some research. I will also continue to look for documentation of a legal name change, but I'm not confident I will find anything.

I'd like to apply as soon as is possible, so spending a considerable amount of time attempting to trace the name change is unappealing. However, I don't want to submit a claim only for it to be denied due to gaps in the documentation.

Any advice would be welcomed!

Give The Hone Office as much as you can. I would try to find the marriage certificate. I know it's a bit tough since they aren't indexed on the GRO.

Some parish records are indexed online and on ancestry websites. Try here? https://www.ukbmd.org.uk/local_bmd

I would go ahead and order your grandparents marriage certificate and her birth certificate. It might help you. The marriage certificate SHOULD list your grandmother's father on it. It could be her birth father (who you could order a British birth certificate for), her adopted father (helps establish the name change), or blank (my experience with genealogy is that is rare).

Her US naturalisation papers won’t be enough I’m afraid. I’d look to find your great grandmother’s marriage certificate before you apply as that’s likely all the documentary evidence there is of the name change.

Did your great grandmother marry your
grandmother’s father or someone else?

My mother-in-law was born in England in 1930 to a 15 year old mother when the minimum age to marry was 16. The next year she married the baby’s father which legitimised the baby’s birth, and they applied for and received a revised birth certificate which had the baby’s father’s name. The original birth certificate did not have the father’s name listed, it was blank.

The advice I was given was to request the birth certificate without too much information and have them search. This worked. The first time I requested it, I ended up with someone else’s birth certificate. My mother-in-law had a super common name.

You might want to ask for advice and help on a genealogy subreddit. People there are super generous with their time and knowledge.

Thanks, all, for your feedback and suggestions!

BritInParis, thanks for confirming that I’ll need to do some more digging. Although I was hopeful I could use what I have, I suspected that might be the case.

aggiegrl, thanks for the tip about just ordering the records. As you had guessed, I was waiting to order everything at once, but hopefully I’ll get some useful info from the birth certificate when it arrives. I also did some digging on the parish records sites that you linked and found a couple of possibilities for great-grandmother’s marriage — unfortunately it’s a situation similar to what pallykin mentioned, where the names are common enough that I can’t (yet) narrow it down.

pallykin, I believe the marriage was to someone other than the biological father. Since I didn’t find any record of the name change, I’m guessing that it occurred post-1945, which would explain why I couldn’t find a record (as apparently would have been required during the WW2 years). But thanks for the tip about requesting the birth certificate with limited information and having them do a search. That will be my next step if the first birth certificate doesn’t give me the info I need.
