Dear Ms. Irvin,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Soundex Index to Canadian Border Entries through the Saint Albans, Vermont, District, 1/11/1895 - 1924 (M1461) and Manifests of Passengers Arriving in the Saint Albans, Vermont, District through Canadian Pacific and Atlantic Ports, 1/11/1895 - 11/30/1954 (M1464) in the Records of the Immigration and Naturalization Service (Record Group 85) that may include Logan Anderson and his passage to Erie. Additional records may be in the Subject and Policy Files, 1906 - 1957 in Record Group 85 that includes a file unit titled Immigration from Canada at Erie, Pennsylvania. For more information about these records, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at email@example.com.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT1. We apologize for this inconvenience and appreciate your understanding and patience.
We suggest that you review NARA’s Resources for Genealogists, as well as the History Hub Blog titled Suggestions and Advice for Family History Researchers. Also, the FamilySearch Research wiki for Pennsylvania Genealogy, particularly its Pennsylvania Adoption Research page, may be useful. If the adoption was held in the U.S., the adoption records will depend on the laws of Pennsylvania where the adoptive parents lived. The process will likely entail contacting the clerk of the court for the county or circuit court in Erie that handled the adoption and potentially the Pennsylvania State Archives. Since the Mahers were U.S. citizens, their adopted child probably would become a U.S. citizen without having to be naturalized. That information may be included in the adoption records.
For information regarding Canadian adoption and immigration records, we suggest you contact the Library and Archives of Canada, 395 Wellington Street, Ottawa, ON K1A 0N4, Canada. Their webpages Immigration and Birth, Adoption and Orphanage Records may be useful as well.
We hope this is helpful. Best of luck with your family research!
