When can I use "further" as a sentence connector? Thank you.

I have a few more doubts.

1) One million people died of the famine (never: one million of people):
2) The uilleann pipes originally known as the Union bagpipe of Ireland.
The uilleann pipes bag is inflated by means of a small set of bellows strapped around the waist and the right arm.
3) The most famous Irish traditional music group are The Chieftains.

The word "further" is not a conjunction; it's either an adverb or an adjective in sentences:

The related conjunction is "furthermore."

1) One million people died of the famine. [or maybe "in the famine" or "during the famine"]

2) The uilleann pipes were originally known as the Union bagpipe of Ireland.

The uilleann pipes bag is inflated by a small set of bellows strapped around the waist and the right arm.

3) OK
