Kendrick family from northern Indiana

I am trying to track my husbands family.His father John Kendrick's mother, Grace Wilson Kendrick died a few days after John's birth and John's father, William left John with some of his mothers family.John had several brother & sisters and we know very little about what happened to them, except for Maxwell who did try to keep track of his siblings.Max died in 1990 in San Diego. I know there was a sister Libby who was a very young girl and was left with a family in Chicago. I believe she took their last name. John had a brother Doug who died in Flordia within the last 20 years.I was hopeing to find some family
