Make sure she knows that the Archive is only open Tues, Wed and Thurs and that she will need some form of photographic ID if she wants to look at original documents. It usually takes a week for them to process a copy so it may be easier (and cheaper) for her to order a copy on-line to be collected when she is there.
In fact I suggest you check out the Archive website www..jerseyheritage.org/ as there are several entries relating to your family. Use the advanced search option and enter surname first, comma, space, christian name. Clicking the binoculars beside the name will bring up a list.
PS What have you done with the weather over here? We flew across the world to get away from the rain.
