Ernest, it would be extremely helpful, for those of us out here wanting to help you or those of us researching the Lamothe surname to know "where". You said in your post you had a funeral home card. What funeral home? Where are you located? Is the funeral home local? If so comtact them for further info. Go to the local library and look up the obit.
My interest is the birth time frame because my grandfather and two of his brothers which I have been able to aquire birth certificate for were also born in that time frame and I have heard they did have other brothers and sisters. They are as follows all born in Concord, Merrimack Co., NH
Frederick Peter b 9 Jan 1885 George William b 3 Jun 1886Known to me as William George Rodolphe Ira b 4 Oct 1891
As you can see your Dina would fall right in line.
