Okay ... This one is a sure thing.
KUCZYN 5243 2232 N Poland 72.1 miles ENE of Warsaw
place is the one you want. Within a mile or so, there are three places named Lubowicz Byzie, Lubowicz-Katy and Lubowicz Wielki. This is in Poland.
The parish for Lubowicz is Kuczyn. There are birth (1890-1899) and death (1891-1899) records for Roman Catholics at the archives in Lomza. Go to this site: http://baza.archiwa.gov.pl/sezam/pradziad.eng.php
. Type in Kuczyn and click on you enter key. Next click on More, and that will give you contact information for the Lomza archives. I don't know why, but the LDS don't seem to have them on microfilm. I do not understand why the archives does not have more years. It's possible that this is a misprint.
