Hi Rosie
Could be. The John married to Sarah might be a brother to Michael.
I have a John, James, Elizabeth, Agnes & Hugh with father Michael (Dorman, Dirman) & mother Elizabeth Gunzion (I'm sure I'm missing children from this generation) and another generation John, Elizabeth, Ann, Jane, Martha, Mary, Susan, Margaret, Jessie, David, Samuel, Michael with father Thomas & mother Ann Neil. Next generation Jemima (died 1877), Mary Ann, Thomas, Samuel, David, Margaret, Michael, Elizabeth Jane, Agnes Jessie and Sarah with father Thomas Dorman & mother Jane (Rainey, Rainnie, Rennie).
My Gunzions - Agnes, David, Janet, William and Elizabeth with father David (Gunzion, Gunnion, Gunyeon) & mother Ann (Gachin, Gaichan) Hugh Gunion/Gunnion wife Mary Cunningham
Would any of these names be there?
Thanks,
Linda
