Hello Christian
Nice to hear from you - I apologise for not expanding on Chorleys BCL - William (Bill) Chorley has published a series of books entitled "Royal Air Force Bomber Command Losses of the Second World War" in various volumes for each year of the war. They are published by Midland Counties Publications and this volume (1944) is under ISBN 0-904597-91-1 and are very popular as they give a day by day notation of operations, broken down into squadron numerical order, with the loss giving information on the crew (including crew positions) and the reason for the loss (where known).
They also supply background information for the period e.g. the Nurnberg raids between 25 and 31 March 1944.
You should be able to purchase via the WWW - try one of my favourites,

With regard to your comment "we have found out that this Group had two Halifax bombers also. Would you happen to know, if they suffered casualties in this area and what unit they belonged to?" - all losses that night are Lancasters on the Braunschweig operation, with a 300 (Polish) Squadron Wellington loss on a "Gardening" operation (Minelaying). However, if you think they might have been lost around the same time please supply a date and I will be happy to search for you.
Here are more details on the 8 Lancaster II's lost that night.
