Lithuanian - English grave marker translation please

[vinito]

Hello.
After a few years of searching, I have found my grandfather's gravesite. There is noone left in our family who understands Lithuanian, so most of the inscription is still a mystery.

If anyone can help, you would make many members of my family happy.
Thanks in advance.

The inscription reads:
