Very little is known about this lodge. The 1913 cornerstone-laying speech mentions that it was organized 2/17/1907, although the Homestead paper claimed it for March 17, 1907 (see article below).
Letterhead used for a document dated 1/28/1919 says they met the second and fourth Sundays of each month at 9:30 AM.
There are undated IOBA by laws with a list of members and a 1928 constitution and by-laws in the Rauh Jewish Archives’ holdings. 1 The book, “Ledgers of Individual Accounts 10/1/1909-9/31/1914,” mentions some deposits for gravestones being paid by IOBA. 2 Some undated documents from the period when Pinkas was rabbi (1931-1944) also mention IOBA. 3
It was mentioned in the papers much less frequently than the IOBB lodge, though it appeared to have some social events.
