Social Security/State Pension

I’m waiting on an attorney to call me back on this, but was hoping somebody on here might have some insight. My Pawpaw passed away very recently and I’m unsure what my Mawmaw will receive in terms of benefits. He drew about $1,000 per month on social security and she drew a smaller amount individually. He also received around $1,000 per month from a state pension (he was a state prison guard). Will she receive a reduced amount in social security and will she be able to draw anything off of his pension? Thanks in advance.
