Any Idea Where To Find A Family Business Dataset?

Hi everyone,

I’m currently working on my master thesis, which I’d like to write about the family-owned businesses. Since it’s going to be an empirical thesis, I thought it would be a good idea to first find a suitable dataset before I narrow down the topic further.

Unfortunately, while I find this topic very interesting, I’m stuck finding a dataset. I’ve only found a few institutes that research on the family-owned businesses and claim to own a dataset, but neither of them is willing to share it (not even under the assurance that the thesis won’t be published).

If any of you have an idea where to find a broad dataset about family businesses (be it rankings, financial data, shareholding, or other relevant numbers), it would be a huge help!

(Obviously, I’m not expecting you to do my work, but my previous attempts weren’t successful, so I’d like to give it a shot here.)
