Report - Change or remove only one chapter heading

Question

I have the following code in my report document:

 \pagenumbering{roman} 
 \setcounter{page}{2}
 \include{Abstract}
 \include{Dedication}
 \include{Acknowledgements}
 \tableofcontents
 ......

and the file dedication includes

\chapter*{Dedication}
\addcontentsline {toc}{chapter}{Dedication}
To Someone

I am using hyperref

   \hypersetup{
      colorlinks,
      citecolor=black,
      filecolor=black,
      linkcolor=black,
      urlcolor=black}

My question is how I can remove the chapter header only for this file, or perhaps change its setting, while leaving other chapter headings as they are.

If I remove \chapter*{Dedication}, I have a problem with TOC, where clicking dedication does not take me to the correct page. Another option would be if I write \chapter*{To Someone}, but in this case I need to change the size of chapter header only for this page, and I do not know how.

Your help is greatly appreciated

Please try the following:

\documentclass{report}

\begin{filecontents}{Dedication.tex}
%\chapter*{Dedication}
\cleardoublepage\phantomsection
\addcontentsline {toc}{chapter}{Dedication}%
To Someone
\end{filecontents}

\usepackage{comment}

\usepackage{enumerate}

\usepackage{multirow}

\usepackage[letterpaper,left=1in,right=1in,top=1in,bottom=1in]{geometry}
\usepackage{tocbibind}
\usepackage[title,titletoc,toc,page]{appendix}
\usepackage[doublespacing]{setspace}


\usepackage{hyperref}
\hypersetup{
  colorlinks,
  citecolor=black,
  filecolor=black,
  linkcolor=black,
  urlcolor=black}

\setcounter{secnumdepth}{3}

\begin{document}
 \pagenumbering{roman} 
 \setcounter{page}{2}

  %\include{Abstract}
  \include{Dedication}
  % \include{Acknowledgements}
  \tableofcontents
  \listoffigures

 \clearpage
 \pagenumbering{arabic}
 \setcounter{page}{1}

 % \include{someChapter}

 \bibliographystyle{plain}               
 \bibliography{MyLib}                      


  \begin{appendices}
  % \include{Ap1}
  \clearpage
  % \include{Ap2}
  \end{appendices}                     

   \end{document}

The stuff between \begin{filecontents} and \end{filecontents} should be the contents of your "Dedication.tex".
