my god... ok, half of this is not understandable, but here's what i understand -
first one:
with great sadness in our hearts to you that I love (..........) love in thoughts with us
the second one is slightly better:
"we lost a wonderful man, a friend, but he will be forever remembered in our hearts and thoughts! sincere condolences from all of us!
In thoughts with you"
It would explain a lot if these letters were written in 18th century? I'm serious.
