i dunno if i spelled it right but its like a sickness that travels from bloodline. like one of my mom relative-cousin their mom have it and like every winter she'll have this sorta 'peeling skin' with her fingers its sorta like ulcer on her skin. and sometimes it happens on their legs to. its sorta of disease but i dunt really knoe how to explain it. >.<Yeah.. Running away together would've been better than suicide.
Idk about the not burying the couple. As you said, they could've just buried their children next to each other and probably even bury them where they suicided.
Btw, whats "mos dua"?
