Headstone for my dad Douglas L. Tackett

I'm trying to raise money so my family can finally have my dad's name engraved on my grandparents existing headstone.  My father was amazing he took on the responsibly of raising three kids that he didn't father biologically.  However he was the best man I've ever known. I want to do one thing to show  that I appreciate his time here with us.  It's been four almost five years since he passed from cancer.  My mother doesn't have the money to get this done and I have five kids and work to provide for them so it's hard for me to raise the money myself.  Please if you knew my dad Douglas L. Tackett any little donation would be appreciated.  As his son I will never feel at peace until we have his name engraved where his ashes lay. He was placed between his mother and father because he wanted nothing more than to one day be reunited with them.  Thanks in advance for any and all donations.
