The correspondence registers are sequenced by "Correspondence Register Subject Numbers" (CRSN). Many of the subjects are convicts and convicts are also recorded in the subjects which aren't convicts e.g. 13737 Invalid Depot which starts at frame 369. To simplfy things we have added two indexes:-
- C53 Convict Index which alerts you to the fact that your person of interest has a least one entry in the C53 Index which you can download and then look up the CRSN's and corresponding frame no's that are of interest to you. These entries are in Subjects that are not convicts.
- C53 Convict Subject Index is more to alert you to the fact that your man has a "Letter_Reg" event on his page with a corresponding link to the relevant page on Ancestry.com in the Citations section
The first entry is on frame 13 on Ancestry.com.
