Hello jacquisim18,
The 1881 census record for Eliza FLEMING or BROWN in the Perth Prison gives her birth year as ca 1841 and birthplace as Kilmarnock, Ayrshire.
The 1857 records in the NAS are for an Eliza FLEMING, native of Glasgow BUT it is interesting that the age of the 1857 Eliza was 17 - a match for the 1881 Eliza ...
AD14/57/52 Precognition against Eliza Fleming, Robert Speirs for the crime of theft 1857 This record is Open
JC26/1857/205 Trial papers relating to Eliza Fleming for the crime of theft. Tried at High Court, Glasgow 1 Oct 1857
Clicking on the reference numbers takes one to further information.
For the first reference:
Eliza Fleming, Age: 17, Address: Residing with Mrs Duffy, Tentine Close, Trongate, Glasgow, Origin: Native of Glasgow Robert Speirs, alias Campbell, Kenneth; Kilwinning, James, Age: 26, Address: Saltmarket, Glasgow, Origin: Native of Greenock, Renfrew
For the second reference:
Eliza Fleming, Verdict: Guilty, Sentence: Imprisonment - 12 months. Note: Pannel to serve sentence in the general prison at Perth.
Do you have other information (census entries, marriage record) for your Eliza?
Regards,
JAP
PS (Added later): I had a bit of a look and found Eliza 2 with her parents in Kilmarnock in 1841, her marriage to William BROWN in 1856, their children - first two (1857, 1859 in Tradeston Glasgow, the rest in Dunfermline). William (a joiner b Dunfermline) & Eliza and family in Dunfermline in 1861 and 1871. In 1881, when presumably Eliza was in the prison, William and 3 children are back in Tradeston Glasgow.
None of this helps with finding what Eliza did which landed her in prison but it's slightly interesting that your Eliza was actually in Glasgow in 1857 ...
