St. Julien A and C are Prunus insititia rootstocks popular in the trade, 
originating in France I understand. St. Julien A has been around for a 
long time, is reputed somewhat dwarfing, compatible with a wide range of 
plums as well as peach and apricot. I gather it is comfortable on heavy 
soils. However there are list members who have personal experience with 
it which I have not.

Your damsons might be suitable as rootstocks and might not.

If you have the space and time and find it hard to get regular plum 
rootstocks, sure, experiment.
