There are no Esther Jeffries in the GRO birth index for 1855. Is this perhaps the correct birth entry for Esther?
JEFFRIES Esther Maria Birmingham 6d 200 Mar 1854 qtr
If you can tell us more about Esther (ie where and when she married and/or, for example, whether she had any other names) we may be able to work back and provide an answer. You must have, at least, some of this information to order the marriage certificate.
There are, of course, several possible alternative spellings for JEFFRIES which we may need to consider.

I do not think that is her. Doesn't the 6d indicate 6 days old? Anyhow, I do not believe she had more than one given name.
The marriage is recorded here on the Births, Deaths and marriages index. Just what is on the certificate is unknown but N.Z. certificates give more information than English ones. The marriage is one of the two absolutes I have. The other is a monument inscription on her grave. For some unknown reason, BDM here does not have a record of her death. I think there may be a name problem there (with the information given at the time of death). However, she was buried as Esther Baker which shows she did not re-marry (and so did not change her name).
I expect the certificate will clear this up.
