You are the only reply, sorry to say.
Yes I am still working on this line and many more.
Here is what I know of this family:
Mary born 1861 married to ? Mcdonald in 1883 and believe moved to Ohio where ? Mcdonald died. Mary returned to Hanover Township with children Jane, Anne, Alexander, William, James, Mary and Cathrine. Believe she married William Biggs 1903 per the 1910 census.
I believe that is the right William in the 1900 census - he is a widow and 2 of his children from the 1880 census with Nancy is Mary age 24 and Joseph age 20.
Depending on who is giving the information to the Census taker - there seems to be mistakes in age, empolyment, etc. I have run across age discrepancies alot, so keep looking for more info to help. Per the 1910 and 1920 census I believe you are close 1952-53.

Good luck in your search
