The name McArthur caught my eye as I have friends by that name living in Holland NY. I contacted them but they are not related to your Margaret etc. I do have the information which will be of help to anyone doing research in the area. Their McArthur family is he only one residing there now The Holland Town Clerk is Sandy Smith. The phone No. is (716) 537-9443. She is very helpful to those needing genealogical information. Information prior to 1870 is limited as fire that year distroyed much early material. She does have a collection of early scrapbooks. Kay
