I suggest google the similar name and find the end user. or estibot supports, but you have to subscribe them( paid). But both the results are same. estibot will check related domain name and give the who is details.
Estibot is a good option, but not the best one, sometimes you must spend few hours on research - google ( very often you can find some PDF documents signed and with contact details, but don't expect to find them on first page on google - 5, 6, 7 etc ) Just type the name of the person + name of the company and end with "email" then click search and "voila" linkedin - is another source, I've got 500+ connection and this helps Twitter and facebook - many people have personal websites and they are listed at social media whoisology.com - this is a paid service, but you can run a search if you know domain owned from the person you looking for
