I was given savings bonds as a gift from family out of state. How do I cash them w/out the primary or co-owner?

There is no way for the primary owner or co-owner to be her b/c they are quite elderly. I need them cashed asap b/c I'm about to have a bababy. How can I get them cashed in w/out there presence, I need the cash right away. Unsure of what to do, the primary owner endorsed some of them. How can I cash them and where?|||If you are not the named owner or co-owner on the bonds, then they are not in fact yours. Physical possession of paper bonds doesn't make you the owner. The named owners have to cash them.
