investigators of the occult

So I was thinking on writting some small story concerning group of occult detectives in a (very) lite lovecraft universe, the basic premise is that diffrent descendednst or more likly relatives get together, now I have two questions, I wanted to included a character from older type of horror, mainly Quincy harker, as such when did dracula took place, is there a chance for him to live during times of lovecraft storys, and two is a litle suggetions what characters should I use, I am pretty sure I will use some Jermyn and probobly West.

Do you mean Jonathan Harker, or Quincey Morris? Dracula was published in 1897, and, I believe, set at about the same time, so it's not outside the realm of possibility that a character from the novel would still be alive in the 20's or '30's, which is what's traditionally considered Lovecraft's era. So long as they survived the end of the novel, of course.

I mean Quincy Harker, son of Jonathan and Mina that is mentioned at the end of the book
