As far as I know, I am not related to him.
His parents were born in Iziaslav, Volhynia [source], which is about 150km from Zhitomir, Volhynia, where I believe some of my Dudelczak ancestors may have lived.
I am a long-time Trekkie. Back in 2007 I posted a photograph of myself from a 1992 or 1993 Jerry Lewis Telethon, wearing a Star Trek uniform.
In 2010 I expressed excitement upon discovering, according to his tombstone, my great grandfather was descended either from Vulcans or Aaron, brother of Moses. (As I noted then, either descent would be equally difficult to trace.)
Nimoy died from Chronic Obstructive Pulmonary Disease (COPD), which he blamed on his years of smoking.
I quit smoking 30 yrs ago. Not soon enough. I have COPD. Grandpa says, quit now!! LLAP

Both of my paternal grandparents died from smoking-related causes. I can't echo his sentiments enough.In November of 2007 I had the opportunity to hear Nimoy speak at the St. Louis Jewish Book Festival. He was there to sell and sign copies of two books: The Full Body Project, a collection of photography, and A Lifetime of Love, a collection of poetry. I brought home the latter.
He will be missed, and remembered, by a legion of fans, as well as by his friends, and loved ones.
