I was in Cork City Library recently and enquired about Cork Jews 1800 to 1840 hoping to get some new information for you. The staff were extremely helpful and I got a little information from "The Jews or Ireland from earliest times to the year 1910" by Louis Hyman publiished 1972.
Quotation-
" Isaac Solomon, the silversmith, is the only Jew known to have stayed on in Cork in the 19th Century. Sir John Carr, the English traveller, found a few Jews there in 1805. West's Directory of Cork and it's Environment (1810) mentions Solomon Hymes (Hyams) umbrella maker, of Broad Lane. Solomon's son Joseph, was carrying on the family business in Broad Lane in 1845, but by 1870 had transferred it to 64 North Main Street, opposite Castle Street. The name of Jacob Hymes, umbrella maker, of 21 Grand Parade, occurs in the Cork Section of the Dublin Directory for 1824, and a Jacob E. Hymes lived in Blarney, Co. Cork in 1870. The Cork Mercantile Directory for 1842-43 gives Solomon Hynes (sic) ladies shoemaker of 1 Royal Arcade, and Mrs. Eliza Hynes(sic) of 61 Douglas Street. In or about 1840 three sisters , Sarah, Eliza and Esther Hyams, arrived in Sydney from Cork and were soon married, Sarah to Lewis, son of Barnett Cohen of London, Eliza to Samuel, son of Henry and Caroline Cohen of Plymouth, and Esther to one Aarons. Before 1835 , a Michael (?) Hyams performed the duty of mohel in Sydney".
Are these three sisters Solomon's daughters?
There is another interesting little bit about a C. Haim a witness at a Schweitzer/Levy wedding in Limerick but it is thought that in all probability that he was from Cork and founder of the Hymes (Hyams) family which first appears in Cork Records in 1810.
Don't know how relevant this is. I am still hoping to visit the Jewish Cemetery at Curraghkippane hopefully in the next few weeks. Will be on again then.
