I am located in Northern Ireland so I have quick and easy access to the GRONI, PRONI and NAI record collections. I would propose 12 hours research time with an additional 4 hours of analysis and report writing.
Dependent on information provided I would be quietly confident of success in finding the relevant records.
I am a registered member of the APG (Association of Professional Genealogists). I would love to work with you on this project to locate your father and grandparent’s information. If you would like to message me any details I can give a more accurate bid and make sure we are a good fit for each other.
