anyone know what this bush & berry is ??

[Guest guest]

I tried to add this photo to my album but wasn't able to do that so I added it

to the group photo's as mystery berry bush. Can anyone here tell me what this

berry bush is ? It is so frustrating because I know I know what this is, my

husband is certain his grand father told him about it years ago, but for the

life of us, we can not remember what it is. The berries are extremely sour. Will

be most grateful if anyone can tell us what it is

 

TIA
