Re: Mary Price
In case you aren't aware of it, you might like to know that the probate calandars are available online through Ancestry. These are the same as the volumes in the library and currently run from 1861 to 1941, whereas the library calendars have a wider range. The calendars include a record of the letter of administration (where a person died without a will) as well as grants of probate (where there is a will to be proved).
The record of grant of probate is often within a year (though I have one that didn't get proved for 20 years!), but a letter of administration can be many years after death - particularly in case where there is little or nothing to distribute.
In recent times, you will almost always need either probate or letter of administration (because there is nearly always at leasr a bank account to deal with), but when there was less rigor and no will, there may well be no application for a letter of administration.
Did her husband die before her? If not, there may be no will/application for letter of administration; I think at this stage a woman's money still became her husband's on marriage (unless a marriage settlement was drawn up to the contrary or the terms under which she had inherited any money specifically indicated that the money was "for her use only"). There were various acts in the 1880s, but the final piece of the legislation that changed that was the 1893 Married Woman's Property Act.
I have looked for Mary Price on Ancestry; I can only spot one within a reasonable time frame and she was "late of Frankley House, 80 Balsall-Haeth Road, Edgbaston". She was a widow when she died on 4th March 1890. Probate was granted (with certain limitation?) on 28 March 1890. I can't spot any other likely candidates at the moment - could this be her?
I hope this helps
