Thanks for your responses.
This post is mainly a shot in the dark, aimed at any distant relative or someone who might be familar with Jewish Cleveland in the early 20th Centruy.
I'm not certain about the death info for Harry. That is the only record I can find for any Harry Bloom with a reasonable date. Odds are slim, but I was hoping it would lead to more records. No luck.
I am looking for more on Harry and Rose both. My hope is to find their descendants, both to connect with long lost family and to see if anyone knows anything about the family further back.
I'm planning a research trip to Cleveland next year in hopes of answering some of these questions. But in the meantime, I'm just trying to find what I can online.
