Looking for advice on the best way to share an obituary in the hopes it finds family.

My grandpa was from Hamburg Germany and has lived in Canada since he was young. For years he kept in touch with his family, my dad's family had traveled to Hamburg when he was young to visit family. In the last probably 25 years or so my grandpa had lost all the contact info he had for his family in a move. They fell out of touch. My grandpa just passed away and my dad was hoping there was a way to share the obituary and maybe an email address in hopes that his family might come across it.

I am looking for any recommendations on the best way to go about this.

I appreciate any insites you can share. Thank you.
