Hoping to find info!

Hi there. I am a birthmom who placed a baby up for adoption through the Gentle Shepherd Agency in Kansas. It wasn't an open adoption, however, the adoptive parents had agreed to send pictures and updates once a year. The baby (Rachel) was born in 1992 and I received this correspondence yearly until about 8 years ago. The correspondence stopped because the agency went out of business. Does anyone know where this information would go once an agency is no longer in business? I am hoping the adoptive parents continued to send the pics & info. I would love to see and hear how her life has been. Thanks for any help you can give.
