Regarding the enquiry re Polish archives, it is possible to do it yourself
but it may take more time. You need to know some basic words such as birth
death etc etc otherwise you get lost, but with those you can figure out a
lot. Many of the archives are not indexed so you need to trawl through
boxes of records. Knowing family names is a big advantage as in the old
days the names followed down through the generations. This is not always
picked up by a researcher.
