Hi Stephanie: I checked my database for information on Lot and Ida Folmar and here is what I show. I'll begin with census information.
1900 PA Census, Clearfield Co. Cooper Twp. Kylertown P.O. Dwelling #80
FOLMER, Lott b Mar 1875 25 married 3 years PA PA PA coal miner
Ida b Nov 1876 23 PA PA PA

The James Dannet Folmar that you mention was also a son of Lot and Ida. He was born 3-11-1908 and died 5-30-1908.
The son that you listed, Archibald Folmar, b 1903 doesn't appear with this family unit in either 1910 or 1920 census. You will need to do some more research on him. I have an Archibald "Dick" Folmar b September 3, 1903 d October 1979 in Williamsport, Lycoming Co. PA who was the son of John Edwin Folmar and his wife Sophia. This family unit according to census is:
1920 PA Census, Clearfield Co. Cooper Twp.
FOLMAR, John E. 46 PA GER Switzerland
Sophia 55 PA GER Alsace Lorraine
Walter J. age?
Ross Bernard Folmar is listed as age 6 in 1910 and age 16 in 1920 making his birthdate 1904 rather than 1908. Do you have a reliable source for the 1908?
I'm not familiar with St. Laurinn's Church. The church records for St. Severin's are not open for public viewing but they are in storage at St. Mary's in Frenchville. The address is St. Mary's P. O. Box 159, Frenchville, PA 16836.
The brother, George Folmar that you question is Lot's brother. The date of death Janaury 27, 1914 agrees with my records.
George and Lot were among the children of Jacob A. FOLMAR b 11-1-1840 d 9-16-1922 and his wife Margaret Elizabeth. One researcher lists her maiden name as GROSS. With the bible records that you posted I would question that name and would do some serious research on the *Schnealt* family under various spellings.
1880 PA Census, Clearfield Co. Morris Twp.
FOLMAR, Jacob 35 PA GER GER
Margaret E wife 35 PA PA PA
Henry A son 15 PA
Francis son 12 PA
John son 8 PA
Sylvester 3 PA *aka Lot Sylvester
Rosannah dau 1 PA
To recap, my basic research leads me to the conclusion that Lot Sylvester Folmar was the son of Jacob A. Folmar and the grandson of Nicholas "John" Folmar and his wife Crescencia Wunderlin.
I would appreciate any additions and corrections for your Folmar family. If you have any more questions, I'll try to answer them.
