My uncle (mother's brother) died w/ no insurance. Mama had already paid for her sister's burial when she died (who she hadn't seen or heard from in probably 30 years) and my brother's funeral in 1981 (he was 21 and had no insurance; Mama only had a $500 policy she had take out when he was little, whiy it waan't more is a long story for another time), so she couldn't afford a whole funeral/bural/etc, esp sinc ehe died in another state so there were extra expenses in moving the body, etc. She hates the idea of cremation, but we came up w/a compromise. The rule in NC at the time was you could bury up to 15 sets of ashes in one gravesite. So, we cremated my uncle, bought a simple urn, had just a graveside service (most of the people there didn't even know him anyway, they just came for my mother or his twin sons (he abandoned the family when they were toddlers in the late 60's) and buried the urn in my brother's grave. I never heard the final amount, but I know it wasn't too bad. Fortunately, when we (me, his sons and their wives) went up to VA to clean out his belongings, turned out he had quite a bit of cash in his checking account (close to $10,000! really long story!!!), so Mama just told the boys to pay the expenses out of it and the two of them keep the rest.
Anyway, it is something anyone can check out w/ their state, buying one plot and burying the ashes of multiple family members in it. I would have never even thought of it had the funeral director not suggested it!
