Who were Agatha Christie's parents?

Answer 1

We are not told who Sherlock Holmes' parents were, but we do have these clues to his ancestry:

In 'The Adventure of the Greek Interpreter' we find this exchange:

__"In your own case," said I, "from all that you have told me it seems obvious that your faculty of observation and your peculiar facility for deduction are due to your own systematic training."

__"To some extent," he answered, thoughtfully. "My ancestors were country squires, who appear to have led much the same life as is natural to their class. But, none the less, my turn that way is in my veins, and may have come with my grandmother, who was the sister of Vernet, the French artist. Art in the blood is liable to take the strangest forms."

__"But how do you know that it is hereditary?"

__"Because my brother Mycroft possesses it in a larger degree than I do."

In 'The Adventure of the Norwood Builder' Watson writes: "A young doctor, named Verner, had purchased my small Kensington practice, and given with astonishingly little demur the highest price that I ventured to ask - an incident which only explained itself some years later, when I found that Verner was a distant relation of Holmes', and that it was my friend who had really found the money."

The Sherlock Holmes stories do not list the names of Holmes's parents. Later books, from authors other than Doyle, have speculated on who his parents might have been. One such speculation produced the names Siger and Violet based upon Holmes using the name Sigerson during his Great Hiatus and his fondness for clients named Violet.

Answer 2

After years of searching through for all the mentions of the fictional Holmes family. Rudolph/Rudy Holmes is their uncle.

Morland & Violet Holmes are the most accepted parents of Sherlock.

However, there are two more parents of Holmes siblings, just not the parents of Sherlock. The only canon siblings are Sherrinford, Mycroft, Sherlock, Sigerson & an unnamed sister.

Sigerson's age varies from source to source. Sherrinford is 9 years older than Sherlock & Mycroft is 7 years older than Sherlock.

Sherrinford & Sigerson are most likely the sons of Siger, the second father figure. Mycroft & the unnamed daughter share the same parents as Sherlock.

Eudoria is likely Morland's second wife & Siger is most likely either a Holmes that died with his wife, Violet, remarrying to Morland or she had an affair with a man called Siger. Eudoria is likely only the mother of Arthur, Enola & maybe Tobias which is why she's probably less keen on Sherlock & Mycroft than Enola in all mentions of the four together.

Sherlock is mentioned as having a dog called Toby.

The unconfirmed but mentioned siblings include:

Shinwell/Binwell Holmes, Eurus Holmes, Nemo Holmes, Arthur Holmes, Tobias who is either a Holmes or a son of Siger, Enola Holmes & Billy [Unspecified parent, maybe adopted, same name as Sherlock's squire].

In total every mention of the Holmes family includes (in order of age): Siger [Holmes?], Morland Holmes, Rudolph Holmes, Violet Holmes, Eudoria Holmes, Sherrinford Holmes, Sigerson [Holmes?], Shinwell/Binwell Holmes, Mycroft Holmes, Sherlock Holmes, Unnamed Sister, Eurus Holmes, Nemo Holmes, Arthur Holmes, Tobias [Holmes?], Enola Holmes, Billy [Holmes?] & Toby the Dog
