The answer is methodical and logical. I wish I'd thought of it! Anyway, thank you for the feedback/direction. Even if I don't find my relative's parents, I feel like I will have made a good attempt by following this advice.
Marcia McCartt was very helpful in obtaining the information I sought. Unfortunately the records did not contain the info I was hoping for but Marcia prepared a report which gave me several other avenues to follow to obtain the info. I will most seek to retain Marcia's services in the future to research my family in Ohio and Pennsylvania.
Thank you so much Ms. McCartt. Your information and tips were quite helpful. I will begin to add your suggestions into my research. Yes, at some point I may require your help. I hope that you will keep your invitation for your services open for me in the very near future. Thanks so much for taking the time to answer my family research questions. Best regards, Rebecca
