Does previous owners family have legal standing?

[Sam Shinn]

Hi BP, I'm seeking opinions not legal advice on how to proceed:

I purchases a tax lien and had a deed issued in 2022. In 2023 I filed an ejectment suit. I named 2 previous owners in the ejectment suit. I was notified by the courts that one owner was deceased. I was recently contacted by relatives stating the last owner is also deceased which happened recently within the last 90 days. So both previous owners named in suit are deceased. 

This is the current issue before me: 

Relatives are now claiming the home belongs to them and have had an attorney reach out to me stating they will be filing something in probate court concerning the will but nothing has come about that in the last 30 days. Ejecment suit filed in 4/2023. Attorney contacted me a week later saying they would redeem home and mentioned he would file in probate but has not filed anything yet. 

A deed has been issued to me. 

What are my options? Home was deliquient on taxes since 2017. I purchased the tax lien in 2019. Received deed in 2022. Filed ejectment in 2023. Previous owner died in 2023. No attempts by any relatives to redeem at all. 

Previous owner lived in home up until death, now children are basically saying home belongs to them. 

I will answer as many questions as I can. Tax sale is not considered void.
