Holmes' (and Mycroft's) Parents

[laurose8.livejournal.com]

Would anyone be interested in sharing their speculation on Holmes' parents, and early life?

Googling got me an interesting article - http://bakerstreet.wikia.com/wiki/Holmesian_Speculation , but there's lots and lots of room left for more. Anything about whether his father worked, or was Army?

I admit I always had an idea that Holmes' early boyhood was in Sussex, and that's why he retired there, but that's more guess than deduction.
