Which Kavacham is good for happy family and having good children

[Arty]

I have been told that Durga Maa is "kanya" and if a married woman worships her, her marital life has ups and downs often

Maa Lakshmi is however her married form and a married woman should worship Maa in this form to have a good family and conceive good children.

How far is this true?

anyway...one suffers from bad spouse and ill-behaved children (or even no children) due to pitr dosha.
Recite Swadha Stotram once every morning which will show effects in long term.
Swaha is for devas and Swadha is for Pitrus.
This is more applicable to a man who :

1. Was raised as an orphan or without father
2. Whose father passed away before his (concerned person) marriage
3. Who is struggling to get married despite being eligible for it
4. Whose father (ancestors) destroyed wealth and left him poor
5. Who got divorced atleast once
6. Who got divorced before having kids
7. Wife(spouse) passed away in young or middle age (before kids become adult)
