Switzerland Recherswil 1850 Census

My surname, Jaggi, originates from Recherswil which is a short distance from Solothurn. One might think that Jaggi is a rare surname. The 1850 census of Recherswil reveals that 1/3rd of the town has the Jaggi surname. Solothurn is worth a visit as it is Switzerland’s finest Baroque Town. It also has a good archive for the Kanton. I found my Ancestors in the 1850 census. Yes there is an 1850 census for the Kanton. I had to take pictures of it with my camera since the books are so large. The census records the wife’s maiden name. It also records occupations. I was quite surprised that the Bern archives has no census records. I came away from the Bern Archives with copies of picture postcards of my ancestors home towns. Try making a google search for census records in Switzerland. I found nothing but vague reference to these records. Is there a reference book anywhere that tells one what census records are available for each place in Switzerland?
