Ending a family legacy four generations long, Margaret Irvine Weir will step down as NexTier Bank’s president effective Oct. 28.

Starting Nov. 4 she will become the director of member services at the Federal Home Loan Bank of Pittsburgh.

Maria W. Smathers, senior vice president of marketing and retail at NexTier, said the bank’s board of directors has not determined if it will pick someone to be president or if it will fill Irvine Weir’s seat on the board.

Meantime, Nextier’s executive management team will share Irvine Weir’s responsibilities, and Don S. Shamey remains CEO of the bank.

This change comes just months from the closing of the merger of NexTier and the Farmers & Merchants Bank of Western PA in Kittanning.

The new regional bank, which keeps the NexTier name, will have about $1 billion in assets and 24 locations in Armstrong, Butler and Allegheny counties.

The Snyder Group of Kittanning has majority ownership in both privately owned organizations.

NexTier Bank, formerly Citizens National Bank, began in Evans City in 1878. In 1907, the state bank charter was changed to a national charter and S.J. Irvine, Irvine Weir’s great grandfather, became the first bank president.

Her grandfather and her father held the presidential title before she took it in 2000.

According to it’s Internet site, FHLBank Pittsburgh provides low-cost funding for affordable housing and community development to 293 financial institutions in Delaware, Pennsylvania and West Virginia.
