Issues regarding Estate and Affidavit of Heirship Recording

My Name is Gladys J. Hildreth. I am one of seven decedents of Minnie O. Johnson (now deceased) our mother. Mother died without leaving a will. Our mother left to me and my six siblings Units of land in the Blackjack Creek Field in Santa Rosa County Florida. The land ( I think) was in the process of being recorded in the Santa Rosa County Clerk of Fl. I have documents that includes where the process is now. At one point Alta Mesa Holding Petro Operating Company managed the account, but no longer has the account. One of my siblings and myself have paid the taxes over the years and now wishes to have the property transferred and recorded in our names . My brother Kenneth L. Johnson ( a retired layer) and myself need legal assistance in making the transfer to our names.
