There are two population lists for the Jewish community of Pyritz/Pyrzyce on Family History Library microfilm #1184446. These lists are part of a collection of records from Jewish communities in Prussia that were microfilmed in Germany in 1944. The microfilms were later copied at the German archives in Cologne, but it is my understanding that the original documents themselves have been lost.
The original microfilms were not very good, and from what we see now, they must have suffered some damage as well.
The list designated as no. 266 is dated 22 apr 1853. It is in good condition. It lists Jewish households by number (but we don't know what those numbers mean, if anything) with the ages of everyone.
The list designated as no. 265 is far more difficult. It consists of 8 sheets, or 16 sides, with individual entries numbered 1 to 319, for 72 households. Because the entries are numbered sequentially, we can deduce how many names have been lost in the illegible sections, due to an ink blot, page 2 not visible at all, parts of page 5 and 15 completely faded (a problem with the original microfilm), and parts of many pages too dark to read. At the very end of this list, however, on page 16, I was able to make out the entry "summa 1865", 72 households and 314 persons, and the next line, "pro 1864", 69 households and 300 persons, then a line showing the results of subtraction, indicating that the community had increased from 1864 to 1865 by 3 households and 14 persons. Thus, the list was created sometime in 1865. From the totals, it is evident that 5 entries in the list of 319 must not have been counted in the total, for reasons that I have not yet discovered -- perhaps there were some apprentices or clerks living in these households who were not Jewish?
List 265 has a column that requests the birth date of everyone under the age of 13. The entries in this column are frequently illegible, but often we can make out the year. A typical entry will say something like 4/10/62 -- this is day-month-year format, 04 oct 1862. Notice that by recording the date of birth for everyone under the age of 13 should bring us back to the 1853 list. I estimate that a total of 50 entries have been completely lost (no usable information).
List no. 265 has a column in which street addresses were recorded, but I have not been able to make out the names of most of the streets. I would be happy to hear from anyone who is able to read the street names and other notations that are not very clear.
I will post transcripts of these lists (or at least, what I can decipher) in the near future.
