My family tree is filling up nicely

however I seem to have quite a few entries where I have found birth details, sometimes even baptism or marriage details but am struggling with dates of death. Most are Liverpool all are Lancashire but it seems much of Liverpool hasn't been transcribed on Lancashire BMD.
What does anyone suggest about tracing people at the end of their lives? I have traced some and even managed to find and visit some graves but feel I must be missing some resources somewhere
