Question

it has also estranged us from our past heritage.(voice change)

Answer 1

Heyaa...

I think your answer will be as follows

---------------------------------------------------------------------------------------------------

# We have also been estranged by it from our past heritage...

# We have also been estranged from our past heritage by it...

--------------------------------------------------------------------------------------------------

@ " From our past heritage"  is the additional information. So, it can be added anywhere...

@ The sentence is in present perfect tense...

@ So the pattern should be $Has / Have + Been + V_{3} form$...

Hope it helps...
