Is there a link between family karma and having Chiron in 4th house?

I agree - it's a really good book.

No - I think you're right with that - I think that's the truth behind the saying - "The Sins of the Fathers...." -

I definitely think so.

I have tons of family karma, due to the extreme stress on
my luminaries and is how I discovered astrology in the
first place. An astrologer who did not know me from a
hole in the ground took one look at my chart and started
asking me about my parents. Her guesses were correct
and when I asked her how she knew that, she explained
the natal placements/indicators in my chart.

I have NN directly conjunct my Cancer Ascendant. My
Capricorn South Node conjunct Descendant drives me
crazy. My family is almost gone but the SN placement
brings expectations out of the woodwork and I see my
family dynamics playing out with other adults who take
on psydo roles in my life. Case in point, neighbors.

My next door neighbors are both disabled. They decided
to adopt two rescued dogs who are huge and aggressive.
One dog in particular kills cats. My neighbors can no
longer walk their dogs, but insist upon treating their dogs
like beloved children. They hired me to walk them every
morning at 7:30. I don't mind at all, it is nice to get out
of the house and enjoy a nice walk with them for some
extra cash as long as the walk is peaceful. Unfortunately,
the Chow mix has already killed a stray cat while I help
lessly watched and freaked out. I was livid, called my
neighbor and told her to get her damn dogs and dispose
of the poor eviscerated cat. Her husband started walking
the dogs after that until he too was made disabled after
the dogs pulled him down because the other one freaks
out at certain cars going by and has to be restrained by
his metal claw collar in order not to run. This dog is
the exact same size as a Saint Bernard, btw. So, I
reluctantly agreed to walk the dogs again for them. I
read somewhere that South Node conjunct Descendant
means people will ask too much of me, and that I will
have to rely upon myself. I could be a bitch and refuse
to walk their dogs for them, but getting another person
to come all the way out to our remote area to walk the
dogs is impossible. I am the only one willing to do it.

The other day, the Chow almost got another cat. I
freaked the hell out and started cussing and screaming.
Of course, my other neighbor across the street who
hates my guts could hear me and probably thinks I
am some kind of a lunatic. All the fucking help in the
world I provide is not enough for them to view me as
a human being. I told my next door neighbor to please
place a muzzle on the chow and she refuses. The dogs
are not a danger to humans, only cats and the occasional
car for some reason. So, true to my nodes I am going
to keep walking the damn dogs for spare cash and I am
going to be seen as the neighborhood lunatic because
that is my fucking karma as far as I can figure.

Thanks mom and dad for all the bullshit. I sure am
glad I did not pass it along to my son. He is living
testimony that I did in fact break the cycle of not
being good enough and feeling ashamed for being
alive.

Very much feel like I have family karma. Also always had a strong interest in researching my ancestors and learning more about them. Chiron is exactly on my IC in 4th house. 

Particularly felt a strong karmic connection to a grandmother. Just looked at her birth chart and noticed we both have moon square Pluto in our natal charts and other similarities. I feel like I face some of the same challenges in life as she did.  She died when transit Pluto was passing my MC. It was a very difficult time in my life.
