Survivor benefits, subsequent remarriage and divorce

You don't mention how long you were married to your first husband. However, if you were married to your first husband for 10 years or more, you may be able to collect disability and/or retirement benefits based on his work record.

Please check this reference :

If your divorced spouse dies, you can receive benefits as a widow/widower if the marriage lasted 10 years or longer and you are age 60 or older (or age 50 if you are disabled.)

In general, you cannot receive survivors benefits if you remarry before the age of 60 unless the latter marriage ends, whether by death, divorce, or annulment.

Please contact your local Social Security office for details.
