Lineage (as I known it as CyanogenMod) saved a lot of old phones for my family instead of going to dumpster. I have a Samsung tablet that has no way of getting latest certificates to go into internet.
I find their supported devices list is quite small, considering, so did your family have devices on that list, or did you experiment by flashing other hardware?
It covers a lot of Samsung and Xiaomi devices, where I live. But you can find other ROMs in xda-developers very easily.
