Help in Warsaw to find certificates

[avilove]

hi
Dear friends
I had a grandfather who was born around 1800 in Warsaw, his name was Klonims (Kalman) Shmuel, son of Ovadia Kimmel, at that time they would use the father's name for the son's name, his daughter Deborah was born in 1822 and I have the certificate,
His wife Cywa Hasfeld was the daughter of Asher, she was about two years younger than him,
my heartfelt wish is to find his marriage certificate, which was in years 1820-1, but Jews do not have separate records, in those years
In addition, I found some of his children
Devora 24/4/1822
The child Moshe - I found it appears in the index as born in 1823 and there is a certificate number 189, I did not find it.
I haven't found my grandfather who was born around 1828-30 and was named Yosef
I haven't found two more children, Neche and Yaakov either, they appear on the death certificate of Kalman the father
I would be very happy to find these missing certificates
And I would also be happy about Ovadia his father, but I have no idea when he died
