Cemeteries in Konigsberg and Lotzen

Hi!
Can anyone tell me anything about the cemeteries in Konigsberg? I have my Grandmothers map which on it she marked exactly where my ggreatgandparents and children are buried. I believe there may be a bldg on top of it now. Also her brother died in '41 and was buried in Lotzen i have pic of his grave also.He was in the military and died of dysentary.
Any info would be SO appreciated! Also how does one go about getting Protestant church records from Konigsberg? Since I can't read German it has been very hard.
Thankyou for any help, (LOOKING FOR MY BECKERS!)

Hi Annie,
we visited Königsberg about 10 years ago. We were looking for old locations where my wife lived as a child as well as the cementary where her father was buried in 1943 (2. Luisenfriedhof). This cementary is still a cementary, but with new (russian) graves replacing the old ones (this is also very normal for cementaries in Germany after about 30 years). There was only a very small part close to the entrance left. The entrance building was still the old one.
We know that another cementary was changed into a park.
Best regards, Uwe.
