Question on tax deed

[Jennifer McDuffie]

First of all thanks in advance for any replies. I'll try do be as clear and thorough as I can with my question. To give a little info....  a woman won some property in a judgement and received a fee simple title. This woman later died leaving two daughters as her only heirs. The taxes on this property were not paid and sold to the state in May 2014. Four months later one of the daughters filed an affidavit of heir ship claiming ownership of the property, but did not redeem. I purchased the property from the state of Alabama in April 2016. I am eligible for a tax deed this May 2017. My question is this... once I receive my deed will there still be a redemption period for the heir ship owner or any other family?  In this case when can I build on the land?  Thank you again.
